Thank you We sneak Inequalities in one variable flashman when
- 00:08
taking a quiz in class or you ever annoyed when
- 00:10
you're asked to come up with a single answer to
- 00:12
a problem curse those test bankers limiting your imagination Wouldn't
- 00:17
it be nice if you could instead supply a range

of answers So you can you know paint with all
- 00:22
the colors of the wind No that song was apparent
- 00:26
Well that's Sort of what inequalities do with equations You've
- 00:29
got the stuff on side exactly equal to stuff on
- 00:33
side b but with inequalities there's room for a bit
- 00:36
more flexibility This if you have a strict inequality one
- 00:42
of these guys here then the value of one side
- 00:46
will be everything higher or lower Then the other like
- 00:50
this And this and this If on the other hand
- 00:53
you have less than or equal to or greater than
- 00:56
or equal to simple your solution would still be arranged
- 01:00
But it would include the given value For example get
- 01:04
a plus one greater than three Then a is the
- 01:08
range of all values that when added one outputs a
- 01:11
value greater than but not including three All right we'll
- 01:14
turn that sucker into greater than or equal to symbol
- 01:18
And now you can include beef Really Inequalities are obviously
- 01:23
simpler when you're only dealing with a single variable in
- 01:26
any time we can further simplifying inequality of one variable
- 01:30
it just makes the range of breck solutions easier to
- 01:32
see Unfortunately when asked to solving inequalities problem test you'll
- 01:37
still probably be asked for just a single answer And 00:01:40.659 --> [endTime] big brother is alive and well
