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

00:19

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
