00:02

Okay sy mash bumpers here's The next problem Evaluate the

00:06

expression Only so we're just going to simplify and probably

00:13

multiply that one third out and then do a little

00:15

bit of squaring and a whole bunch other men All

00:18

right So here we go Emcee essure this guy this

00:20

is some of his artwork Said we adore chaos because

00:23

we love to produce order with wisdom of this thought

00:27

about the importance of order has only been rivaled by

00:29

sir top um at the controller of the railway on

00:32

thomas and friends who noted that without order there's on

00:35

ly confusion and delay Surely both these wise men were

00:39

inspired by the order of operations here as always starts

00:42

simplifying parts The expression located inside the parentheses these guys

00:45

right here that's nine months five plus two the addition

00:48

and subtraction should be completed from left to right because

00:51

while they're really the same thing subtracting a value is

00:53

the same is adding and negative And don't get derailed

00:56

by following pim does literally even though the a for

00:59

edition comes first in the acronym subtraction is performed first

01:03

here because it's the first operation to appear So i

01:06

was doing it left to right like a typewriter So

01:08

we get one third time's quantity four plus two than

01:12

that thing squared plus four times two and let's keep

01:14

simplifying Got one third time Six squared plus for seeing

01:18

will keep chugging along and that's the third time's at

01:21

thirty six there plus four times Two We're almost there

01:24

channel the spirit of the little engine that could do

01:26

the order of operations and multiply next Alright keep in

01:29

mind that multiplying thirty six by a third of the

01:31

same is dividing it by three That gives us twelve

01:34

plus the four times two there's eight we just adam

01:37

up its twenty The value of the expression is twenty

01:39

c Well em see mr asher There may have been

01:42

a famous mathematical artist but thomas and friends as weii 00:01:45.917 --> [endTime] catch your quotes
