Okay sy mash bumpers Never one for your own expressions

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
Full Transcript
- 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
