sometimes when you're sitting in math class you might wonder

00:16

will this math ever help me in the real world valid question math won't

00:21

ever pick you up from school or buy you coffee or drop you off the airport but [student day dreaming in math class]

00:25

all that aside math is still really helpful in our daily lives especially

00:28

addition and multiplication sorry subtraction and division we love you too [substraction and division symbols bouncing on the screen]

00:32

so let's imagine we're taking a trip to the supermarket when we're shopping it's

00:37

important that we know how much everything costs right after all take

00:41

everything you want for free specials are pretty rare so maybe you want to buy

00:45

a bottle of shampoo that cost $5.50 and maybe you also want to buy some [bottles of shampoo on the supermarket shelf]

00:50

conditioner which costs six bucks and how much will you need to pay to buy

00:54

both items luckily for us we don't need a rocket scientist to help us figure out [a lady in a white jacket with a rocket nearby]

00:58

the answer though they do always seem to know the best deals on hair care

01:02

products no all we need is addition we just add the two prices together which

01:07

gives us a total of eleven dollars and fifty cents bingo even easier than

01:11

[woman in the shower washing her hair] washing your hair now let's say that instead of buying two different things

01:14

we wanted to buy a bunch of the same thing like watermelons the price at this

01:18

supermarket is three dollars per watermelon so how much would it cost if [an array of watermelons in a supermarket]

01:23

we wanted seven we could try adding the prices of all the watermelons together

01:27

but that would mean a lot of additions and we just want to spend an afternoon

01:31

at the beach eating watermelon not an afternoon at the beach adding numbers [a man scirbbling on a notepad]

01:34

together the sand isn't great for our calculator luckily we can just use

01:38

multiplication since we have seven watermelons and they each cost three

01:42

dollars we can multiply three dollars by seven to give us our cost of 21 dollars

01:46

how do we actually get those seven watermelons home is a different much [a cicycle wheel and a backpack carrying watermelons]

01:50

more difficult problem hopefully somebody gave you a ride to the

01:53

supermarket yeah never count on math to pick you up
