Coming soon from is a virtual big series ten by the enemy army is on the horizon.
How many do they number?
3 million.
700,000 might get.
And how many do we number ten make it ten.
Any one of my ten Spartan soldiers is as good as 20 person.
Don't you think they'll have to take out a lot more than 20 Persians, my lord.
More than 20 each.
How many?
How many must each of my brave soldiers battle with?
You are asking us.
As a percentage we can use the number ten Spartans to figure out how many Persians each of us must fight.
Do you see making no, you see.
To take a percentage of ten, you have to move the decimal point one place to the left like this.
If you have 3,700,000, you move the decimal point to one place to the left and you get 370,000, which is the number of Persians each of our men has to kill 370,000 persons per man.
I like those odds.
So that's good.
My King, this is mad.
No, this is best guess.
When making money is the aim.
These if they bring that game, that means should you do it?
Now they know what happened.
Let you know just how to make that go and that last right.
Wow.
So learn a little more than Vegas.
Manage the dough and shadow.
Brought to you by the members some today.
It's lamb.
Pardon me.
You know, most of the math you need for business, you probably learned in grade school.
Grade school.
Or earlier.
Do you know how to figure out how much money you.
Yeah, sure.
You just add it up.
Okay.
So you probably learned that around, what, kindergarten?
First grade.
Right?
So do you know how to figure out how much money you have left over when you buy something or how to make change when you sell something?
Yeah.
Duh.
Subtraction.
I also learned that in first grade.
Exactly.
So let's say you know how many hours you work and how much you get paid per hour so you know how much you'll get in your paycheck.
Multiplication third and fourth grade.
So what about percentages like tips or discounts?
Decimals, which I think was around sixth grade.
So you're saying every time I use money, I should think about my grade school teachers.
Like math is coming up next.
Take stage.
Yeah thanks, dawg.
Well, you could look at it that way.
It also shows that it's not that hard.
Even a grade school kid could do it.
Here's my dollar.
Yeah.
These market day, the money's fake, but the math is real.
What happens today at the third grade market at one elementary is on the third graders.
So thanks to the second graders, for a certain amount of money.
I'm going to go spend some money and see the future.
Money is speak with the math is really.
The basic money.
Math concepts that they learn are addition, subtraction, making change and estimating money value.
I'm a seller today at the market and I'm going to be selling brownies.
I saw Brownie for $0.50 today.
We are sellers and so for Dominic $2 the customer is half off, which is dollar.
The price was $0.50 before, but I cut it to $0.25.
I give a 50% discount.
People started coming.
Thank you.
Enjoy your brownie.
Adding up the money.
But you have like 50 cent pieces.
$1.25 cent pieces is important.
So you know how much money you've earned.
I hope to make a lot of money.
Even if it's fake money.
It's not getting now more.
Days over and I'm counting my money.
I need about $21, $38.
I thought I'd only make $10.
My estimation of $25 that I would make, I got I was kind of wrong about that.
I made $18 more than I thought I would have these kids.
Now, your math, you might not think you need to know money to get along in life, but I guarantee you you'll be a lot more successful.
They've also.
It's my assistant, Brian.
Oh, my clients, they go cheap.
That's because you're a lousy tip.
A Brian.
We're talking basic.
Money mafia, simple percentages.
Add it up.
Hey, I'll see you guys later, okay?
Hey, hey, hey.
Where are you going?
I have a date, remember?
Well, a date is the perfect opportunity for us.
Talk about tipping.
Let's say you and the BF have just finished a really nice meal.
Then the bill comes and it's time for you to figure out the tip.
The amount of the tip depends on the percentage of the overall bill.
And the overall percentage that you use is based on the quality of the food and service.
Usually it's 10% for a fair, 15% for good and 20% for great food and service.
Okay, great.
Doing the math for the tip is easy.
Say your overall bill is $25.
You just move the decimal point over one spot and you get to 54.
Great service, just double the amount to $5.
That's the basic rule of tipping.
So you can adjust it any way you want.
Okay.
Well, thanks to the tips on tipping, but I really.
Got to go.
Hold on one more tip.
Don't forget the doggy bag.
You know, that was kind of fun.
A biscuit.
You're going to need some money, math to get on the green for bananas.
And he's like, I'm a golfer and I invest in the stock market.
The stock market is really founded on the basis of math.
I learned that I could gain money rather than have it depreciate over the years.
So in golf, as you get closer to the pin, just as in finance as you get closer to your target, which ultimately is retirement, you want to be more conservative in your investment and in golf you use a shorter club and it doesn't go as far, but you're able to be more accurate with it.
Steps up, steady, beautiful.
Beautiful.
One in mathematical calculation used in finance is the price to earnings ratio.
P e ratio p e ratio.
Just kidding.
It is the price per share of the stock divided by the earnings per share of the stock.
And that calculation is used to determine the value of the stock.
And, you know, if it's overvalued, undervalued, how it may perform in the future.
Golf is just like the stock market.
If the market goes south and you find yourself in a trap, it may be time to dig your heels in.
And remember, you can always recover.
Young man digs, he heads in.
Oh.
Certainly.
Math is fundamental in understanding the stock market and investing in general.
And the more math you know, chances are, the more successful you'll be ratios and percentages and relating those to actual numbers are fundamental concepts and elementary.
And everybody should note, including you.
Math teachers can use vocational examples without watering down the concepts.
What better way to drive.
Home the importance of geometry.
Than to show that not only the mechanical engineer and the draftsman, but the crane operator determining the safe lifting capacity of his machine depend upon its principles.
In a world where dollars and cents can sometimes make little sense.
Help will come from the future.
The calculator.
Come with me if you want to compute balls, man and machine.
His mission is simple.
Save the world from faulty money, man, I can.
This is 20% off.
$35.
That's is one fifth.
Can you divide by five?
Yeah, 35 divided by five is seven.
That's is $7 off.
That's a good deal.
And I don't know how much it's going to cost after the 8.1% sales tax.
Round up calculator at ten.
So 10% of 28 is about $3.
And three together is $31.
I have enough and possibly enough for a large had food court.
Come, we must buy this blouse.
Marty Spence.
Nicole stars in the calculator.
I will crunch those numbers.
Math is for losers.
Everybody knows that.
Oh, you think so, do you?
Yeah.
And what do you want to be when you grow up an astronaut?
What about when you've miscalculated.
Your trajectory around the moon and you have to recalculate or else you're flying to the hot sun?
Ha ha.
Did you ever think about that, huh?
Did.
Yeah.
And math was my worst subject.
Hm.
Nice things there for my mom.
How much do you think it cost?
Looks like $25.
Well, look at how much it cost for me to buy them.
But how much do you think it costs the store to sell them?
To sell it?
Yeah.
It's called the seller's cost of production.
Essentially, it's the cost of transporting ocean and supplies and employee wages and daily operational costs.
Pretty much all the costs it takes to make one unit of your brand.
Okay, so let's see if I get this.
In this case, the supplies would be the flowers, the base and the ribbons and stuff.
So they had to buy that stuff and have it shipped to them.
So that added costs and then someone at the store had to put it together.
So that's wage costs.
And to keep the store open every day, that's operational costs.
You got it.
And the seller's cost has huge impact on business because it decides if a store is capable of making a profit.
I thought these were for your mom's birthday.
Yeah.
Congratulations on your wedding.
What?
Don't just run a business with an adding machine.
Well, you don't just run a business with a crystal ball or a rabbit's foot.
Lava bags.
Yes, lava bags.
Well, for us, it's money bags.
Yeah.
Hi, I'm Laura.
I'm the owner of Love of Mexico, where every bag is unique.
I just started sewing on my own, and I started making bags for the school just to hold books and stuff.
And I took them to school, and my friends really liked them and they started ordering for me.
I read somewhere that clothes can't be recycled very easily, so cutting them up, making them bags was that was a great idea.
But I buy my accessories in bulk.
Time is money.
I like to go to thrift stores.
I get just old clothes.
Like some old shirts are great.
My neighbor gives me tons of great fabric.
My friends donate belts and scarves.
Time is money.
I make my bags for $8 a dollar 50 for my fabric, another dollar 50 for my accessories, $5 for my time.
And I sell them for $20 and I make a $12 profit that's over 55% in profit.
One, this is Alex Rattray, my business partner.
And the math was really slow.
He said that we should apply to the state and we can make this company really big, expand and go commercial and just have a great time doing it.
Pretty soon we're going to start selling to stores because a lot of people go to stores that we don't even know.
So we reach our much larger market.
The stores have other expenses, so we're going to have to sell to them for a little bit less money.
But that doesn't mean that we're going to be earning less money in the long run because we're going to be selling so many more bags.
For example, if we were to sell 20 bags to some friends for 20 bucks each, you know, we'd make a good deal of money.
But if we sell 300 bags for $15 each for a store, we're still going to be earning a lot more money.
So we started out with me getting 10% of the profits and her getting 90% of the profits out of every hundred dollars that we earned in profit, she'd get 90 and I'd get ten bucks.
But then we realized I was doing a lot more work than I thought I'd be doing.
So we switched to 25%.
75%?
Oh, I ordered a bag.
Oh, she gets $75 out of every hundred dollars that we make in profit and I get $25.
Maybe I should start negotiating and.
Walk off for.
$8 expenses.
$20 revenue.
That's $12 profit.
Wow.
That's money.
The bag.
Hey, 25%.
What else can math do?
A lot.
It can help you with finances.
Maybe I was wrong about math.
Well, tell me, are you need to get your dollar double without.
Any crap about.
Your bed and then look at it.
Yeah.
It's what you need to give your body graph.
It's not easy.
Now the rules that make you hey man's.
Head now the rule of savvy chair.
Look, this whole math thing maybe you're seeing all right, but I like to be with the action is I like big I like big movies I like big things.
You know, my not really my thing.
Are you an idiot or do you just play one on TV because I'm talking about how to double your money.
Your money?
Talking about a secret scam on.
Well, I'm all ears.
No, no, it's not a secret scam, but it is really simple.
Let's say you have an investment that has an interest rate of 7% annually.
You just take 72 and divide it by seven and you get.
1.2.
Yes.
Yes, that that's right.
That's how many years it would take for you to double your money.
You know, you're not so bad at this math thing, after all.
For you trying to blow my cover, I'm trying to be cool.
And you just keep on to real savvy.
Do just remember, take the interest rate and you divide that into 72 and it'll work every time.
Oh.
Pens it.
All right, well, the map says you need to cross this, but you quit with the coconuts.
All right, so the map says we need to cross this bridge with a big, scary man on it.
What big, scary man?
That one word right there, he's.
He's waving around.
Yeah, that one.
All right, so I think I'll go fast, dismount it quick.
Honestly, nothing but three straight days.
A killed, missing property, competent, honest.
Let's try top.
What is your name, sir?
A lot.
What is your question?
I need to stock my own business.
What is 20% of 250?
25.
That way I'm to.
All right hold on.
Next stop.
What is your name?
So, Robin.
What kind of a name is that.
The one my mother gave me?
What is the rule of 72?
The.
The rule of what?
You see your next May?
Yeah.
You got.
What is your name?
So, Chet, what is your quest to get across this bridge alive?
What are the odds of putting Penny out of a stack of 100 coins?
All right, it all depends.
You have to be more precise.
How many pennies are in the stack of 100?
I don't know that out.
That goes pretty smart.
The point is, you need to know basic money, man.
We're talking addition, subtraction, multiplication, division, percentages.
These are basic skills that will help you through your entire life.
And if you can figure that out, your life will be pretty sweet like this.
Guys, I'm the start again owner and let me start again.
CBC Chocolates is currently a pulse based company that I own almost all of.
I was 15 years old.
I had the idea to start a chocolate company.
After taking a culinary arts class, I began experimenting with unique flavors to find a product that was unique and that could differentiate myself.
I decided what I needed to do was find a way to sell more chocolate.
I wanted to make enough money to be able to afford to go to college, and that way was going to be to sell wholesale for each wholesale customer that I have.
I have to add, I don't need to have nearly as many retail customers, less customers, more volume per customer, more profit.
I guess it's time to make some chocolate.
I've always enjoyed math, especially the type of math to figure out cost and profit margins and all those type of things.
This box costs about $14 to make before all of my overhead expenses.
This box has 30 truffles in it, three different flavors, and each of those truffles has a different cost.
I have to know the cost of each, the ingredients in each one of the three different chocolates, the cost of the labor for each of the three different chocolates, and the cost of putting the whole box together.
So that includes all the different packaging costs, including the lid, the base, the label, and this nice little silver loop here.
So all of those costs have to be taken into account.
Since I've determined that I need a 25% profit margin, I end up with 1867, which is my wholesale price, which is the cheapest price that I can sell this product for two other businesses.
Once I sell the product to them, they have to be able to sell it for a higher price that in order for them to make a profit as well.
So I calculate that price based on numbers that they give me on how much of a profit margin they need.
Those numbers are usually around 40%.
So if you take the 1867 that they paid for the product at 40% to it, you end up with right around dollars.
So that's just the price that I put on the box for them to sell the product for in order to do the type of calculations that are necessary to figure out these type of costs.
It really requires no more than sixth or seventh grade math.
You know, it's really fairly simple stuff.
I've gone through AP calculus, but I certainly don't use that every day in order to calculate the cost of wholesale goods.
This is the 2008 NFIB and Visa Young Entrepreneur of the Year award, and I wouldn't have been able to win it without my math skills.
This advertisement says that the price of this car is $200 over wholesale.
But what's wholesale?
Wholesale is?
What the dealer pays the distributor for the car.
Oh, so wholesale.
Is the price of the car that the manufacturer charges?
Not necessarily.
Most things go from the manufacturer to the retailer through a distributor or wholesaler.
That person sells the product to the retailer.
And that sounds like what my dad calls a middleman.
Well, that's another term for it.
Basically, someone in wholesale buys big bunches of things and sells it in smaller portions to other groups.
In order to make a profit from it, the wholesaler has to sell for more than what they paid for it.
So if I wanted to wholesale, I could buy a car for a lot cheaper than if I bought it from a dealer.
Well, sure, but you'd have to buy 100 of them.
Oh Everyone along the line has to make a profit.
That's business.
And whether you're in retail or wholesale, you need to know basic math so you can calculate a profit.
Why do so many businessmen ignore it?
We choose not to destroy Carven, Jamie, Zach, Laura, Emily, Joseph.
And we made the coolest clothes challenge.
Math definitely was a huge part of this project.
The Cool Schools Challenge is where we go around and work with teachers on reducing carbon dioxide within the school building and in their daily habits.
Turning off lights using reusable water bottles and recycling.
Those are things that lower our cost.
We started out by going to the teachers and basically recommending simple behavioral changes that they can make.
Which when we started to approach the teachers, we brought, we brought in these forms.
And these are basically to help them figure out how much carbon they're currently using in their classrooms and what the best ways for them to reduce that use it.
It has some basic questions that you would ask.
For example, is there a adjustable thermostat in the classroom?
Does the classroom recycle?
This is the category of energy vampires and.
It has all the appliances, a classroom I have.
How many?
If the teacher turns it off, if they leave it plugged into the power strip is still turned off and you just check the box.
After we finished our post survey, we went back and we looked and we saw that every box checked had a conversion factor and you're.
Saving about six and a half pounds of CO2 just by turning one light switch off day.
Every step involves some sort of massive scale that you learned more times.
We just had to calculate, and that gave us the total for each category.
And then it's just a matter of adding up the total in each category to give you a grand total for each classroom.
And then once you had each classroom, you added all those together to get the grand total for the entire school.
We found out that we had reduced our schools electricity bill by over $15,000.
The numbers were astounding to all of us.
And the thing, the beauty of this whole project was it didn't cost us the school district of Penn.
All it was was strict conservation.
To date, the school's challenge has about 20 participants, and those 20 schools have saved Washington State about half a million dollars.
The schools challenge the President's Environmental Youth Award for our project in school.
You never really think that a lot of the skills you learn are applicable to your day to day life, but they really do affect you.
Calculating how much money you save along with how much CO2 you save using your math skills can be really amazing to see.
It was really a great correlation how we could use the math that we've learned since since first grade to help save the world.
And now it's down to this kid's math quiz.
What is this show about?
Let me count the ways.
One random money math situation to you need money math to be successful in life.
Three street hockey for Brazil nuts.
If you answered one or two.
Congratulations.
You're this kid.
If you answer three or four, well.
You must have been counting players, counting goals.
You're counting nuts, right?
And now it's time for another you are submitted video.
Yeah, that's right.
Do the math, baby.
Money, math, baby.
You know what I'm talking about.
With this kid?
Lucked out.
Math whiz decimal point said is a young mathematician making decisions with the medical visions.
They they'll get ecstatic so acrobatic when it comes to mathematics math is what I got.
Well it's nine tons for it's the one you gotta tell him about the number.
Wrong.
I'm going to tell him about the numbers.
Tell him about the number.
I'm going to tell him about the numbers with his kids is the win with his kids.
We is in the win with these kids.
Which is a win for his kids, which is a little bit.
So we're almost to the end of our show on math.
My favorite subject.
Come on even.
You can see it's not just a bunch of numbers, it's business.
Right.
And not just.
Big business, but your business to.
Understanding interest rate so you can find the best savings account.
Now that's a good thing.
Knowing percentages cost per unit, wholesale retail.
Good to know that too.
But it's also important to make sure you get the right change.
It's still just a bunch of numbers and those numbers are your money.
So remember, when it comes to big business or just money in your pocket.
Mathematics matter.
Hey, that's good.
Can you say it again?
Mathematics matter.
Faster.
Mathematics matter.
Master Mathematics matter.
Mathematics matter.
Mathematics matter.
At math.
Okay.
Okay, that's good.
That's enough already.
Last time.
Ten, ten then that's good.
Let's go get them boys.
Heard.
Oh, wait, wait, wait, stop, stop, stop.
Now net stops.
Yield is blocking my process.
This is 20% off of $35.
Never mind 41.
Oh, I forgot my sword.
You guys wait here.
I'm going to be back in 2 to 3 days.
All right.
So now you've heard some of our stories, and we want to.
Hear some of yours.
Maybe you are a friend that started your own business or thought of some ideas to help the community.
Yeah, we want to hear about those.
So going to this kids dot.
Com and share the good news.
Who knows?
Maybe you'll end up right here on the show.
Well, not exactly right here, but yeah, on the show.
All right here?
No, not really.
Kind of right here.
No, not there.
