Thank you We sneak in and here's your shmoop du
- 00:05
jour brought to you by the term undefined it's What
- 00:09
mathematical operations declare Is there major at college when they're
- 00:12
not sure what they want to do with their lives
- 00:15
All right what operation would make the following expression undefined

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
