Okay sy mash bumpers Never one for your own expressions

00:05

Here Evaluate this one Well when we order a cheeseburger

00:13

we expecting ingredients to be presented in a certain order

00:16

right There should be a piece of bread on the

00:18

bottom than a burger than cheese lettuce ketchup all top

00:20

with the second piece of bread and maybe some special

00:23

sauce underneath that But don't ask it's special They can't

00:26

tell you what it is You'd be no good to

00:27

have a bun sandwiched between a meat patty and lettuce

00:30

that's what it looked like and get all messy and

00:32

kind of gross All right we're gonna start inside the

00:33

princes inside these things there's subtraction addition going on because

00:37

attraction in addition or technically of the same status while

00:41

subtracting is really adding a negative well their work from

00:44

left to right So we've got five minutes to plus

00:47

three all inside the prince he's there squared divided by

00:50

three ten times too So you gotta remember going left

00:53

to right here We've got to do all these operations

00:54

in order So inside the prints we have three plus

00:57

three squared So that's six square divided by three times

01:00

too All right next on the menu is the exponents

01:02

six of the value that's being squared we've got thirty

01:05

six then divided by three All right so we're going

01:08

to finish off this tasty little burger by completing the

01:10

division and multiplication They remember that hope him dusting These

01:14

operations are also basically the same thing Like division is

01:18

multiplication by a fraction So yeah there work left to

01:21

right So we take thirty six divided by three that

01:23

gets his twelve and then we take twelve times two

01:25

twenty four so that's it The answer is d remember

01:28

pim dos the acronym for the order of operations right

01:32

Parentheses and like stuff Yeah well that can cause indigestion

01:36

if it's followed literally inside the parentheses The operations are

01:40

completed from left to right because they're the same same

01:42

status right You can't be a later on division comes

01:45

before multiplication because it also comes first in the expression

01:49

and the experiment applies to the entire quantity in the

01:52

princes not on ly the three which is where you

01:54

would have gotten sea right now for the hard work

01:56

Should we order a strawberry or vanilla shake What are 00:01:59.473 --> [endTime] we thinking All right wait
