seven divided by ones Okay well let's assume this question

00:26

isn't asking us about a type of surgical procedure because

00:30

i'm not sure a triple bypass is gonna do the

00:31

trick here Instead we've got four options plus minus times

00:35

were divided by before we start plugging stuff in willy

00:38

nilly Let's ask ourselves what we're really trying to find

00:41

here What does it mean when something's undefined Well the

00:44

most common i'm defined thing you're going to have on

00:47

a test like fish is once something's divided by zero

00:51

You can't really divide something by zero no matter how

00:53

hard you try which is what makes an expression undefined

00:55

in first place In that case we can set up

00:57

a little equation one blank one equal zero with the

01:01

blank being the operation we're looking for so it should

01:04

be pretty obvious that one minus one is zero and

01:06

when we take seven divided by zero we're undefined which

01:09

is what we wanted So our answer is minus there 00:01:12.806 --> [endTime] that wasn't nearly painful is a triple bypass Oh
