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

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
