Thank you We sneak And here's your shmoop du jour

00:06

brought to you by the term undefined it's what mathematical

00:10

operations declare Is there major at college when they're not

00:13

sure what they want to do with their lives All

00:15

right what operation would make the following expression undefined seven

00:20

divided by ones Okay well let's assume this question isn't

00:26

asking us about a type of surgical procedure because we're

00:30

not sure triple bypass is gonna do the trick here

00:32

Instead we've got four options plus minus times were divided

00:36

by well before we start plugging stuff in willy nilly

00:39

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

00:42

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

00:45

common i'm defined thing you're gonna have on a test

00:47

like fish is once something's divided by zero You can't

00:51

really divide something by zero no matter how hard you

00:53

try which is what makes an expression undefined in first

00:56

place In that case we can set up a little

00:58

equation one blank one equals zero with the blank being

01:02

the operation we're looking for So it should be pretty

01:04

obvious that one minus one is zero and when we

01:06

take seven divided by zero we're undefined which is what

01:10

we wanted So our answer is minus there That wasn't 00:01:13.314 --> [endTime] you Jewel is a triple bypass Oh
