alright<00:00:08.330> looking <00:00:08.540> at <00:00:08.660>things <00:00:08.780>in <00:00:09.020>a - 00:09
alright looking at things in a - 00:09
alright looking at things in a different<00:00:09.200> way <00:00:09.650>can <00:00:09.980>help <00:00:10.190>us <00:00:10.340>better - 00:10
different way can help us better
- 00:10
different way can help us better understand<00:00:11.150>
them - 00:11
understand them
- 00:11
understand them for<00:00:11.600>
example <00:00:12.050> have <00:00:12.559>you <00:00:12.650> ever <00:00:12.769>known - 00:12
for example
have you ever known - 00:13
for example
have you ever known a <00:00:13.130> headstand <00:00:13.700>in <00:00:13.849> your <00:00:13.970>bedroom - 00:14
a
headstand in your bedroom - 00:14
a
headstand in your bedroom yeah<00:00:15.290> well <00:00:15.559>that's <00:00:15.830>one <00:00:15.980>way <00:00:16.070>of - 00:16
yeah well that's one way of
- 00:16
yeah well that's one way of doing<00:00:16.339>
it <00:00:16.519> way <00:00:17.179>back <00:00:17.539> in <00:00:17.810>elementary - 00:17
doing it
way back in elementary - 00:17
doing it
way back in elementary school<00:00:18.650> we <00:00:18.769> learned <00:00:19.070>that <00:00:19.099> five <00:00:19.369>plus - 00:19
school we
learned that five plus - 00:19
school we
learned that five plus three <00:00:19.699> is <00:00:20.060> the <00:00:20.210>same <00:00:20.480>as <00:00:20.630> 8 - 00:20
three is the same as 8 - 00:21
three is the same as 8 they<00:00:21.470> look <00:00:21.829>different <00:00:21.949>but <00:00:22.400> they're - 00:22
they look different but
they're - 00:22
they look different but
they're equivalent <00:00:23.060> is <00:00:23.659>same <00:00:24.050>value - 00:24
equivalent
is same value - 00:24
equivalent
is same value well<00:00:25.039> it's <00:00:25.159>kind <00:00:25.339>of <00:00:25.369>the <00:00:25.460>same <00:00:25.489>thing - 00:25
well it's kind of the same thing
- 00:25
well it's kind of the same thing we're<00:00:25.970>
talking <00:00:26.300>about <00:00:26.390>here <00:00:26.630>except - 00:26
we're talking about here except
- 00:27
we're talking about here except now<00:00:27.349>
we <00:00:27.649> learned <00:00:27.980>that <00:00:28.009> two <00:00:28.339>x <00:00:28.550>plus <00:00:28.579> 6 - 00:28
now we
learned that two x plus 6 - 00:29
now we
learned that two x plus 6 can<00:00:29.269> also <00:00:29.509>be <00:00:29.689>written <00:00:29.839>as <00:00:30.109> 2 <00:00:30.319>times - 00:30
can also be written as
2 times - 00:30
can also be written as
2 times the<00:00:30.679> quantity <00:00:30.769> X <00:00:31.429>plus <00:00:31.880>3 <00:00:32.300>are - 00:33
the quantity X plus 3 are - 00:33
the quantity X plus 3 are why<00:00:33.649> do <00:00:33.769>we <00:00:33.859>need <00:00:33.980>to <00:00:34.100>look <00:00:34.250>at <00:00:34.370>an - 00:34
why do we need to look at an
- 00:34
why do we need to look at an equation<00:00:34.910>
in <00:00:35.090>different <00:00:35.539>ways <00:00:36.140>mm - 00:36
equation in different ways mm
- 00:36
equation in different ways mm
well<00:00:36.890> maybe <00:00:37.519>we <00:00:37.670> need <00:00:38.000>to <00:00:38.090> divide <00:00:38.660>the - 00:38
well maybe we need to divide the - 00:38
well maybe we need to divide the expression <00:00:39.320> by <00:00:39.469>2 <00:00:39.829> which <00:00:40.070>is <00:00:40.129>easier - 00:40
expression
by 2 which is easier - 00:40
expression
by 2 which is easier when <00:00:40.789> it's <00:00:41.000>factored <00:00:41.480>app <00:00:41.750>or <00:00:43.340> maybe - 00:43
when
it's factored app or maybe - 00:43
when
it's factored app or maybe well<00:00:43.910> we <00:00:44.120>just <00:00:44.359>wanted <00:00:44.570>to <00:00:44.750>look <00:00:44.899>at - 00:44
well we just wanted to look at
- 00:44
well we just wanted to look at
the<00:00:45.079> number <00:00:45.289> three <00:00:45.559>it's <00:00:45.859>sort <00:00:46.010>of - 00:46
the number three it's sort of - 00:46
the number three it's sort of peaceful <00:00:46.519> looking <00:00:46.969>well <00:00:48.379>when <00:00:48.589>you - 00:48
peaceful
looking well when you - 00:48
peaceful
looking well when you stare<00:00:48.949> at <00:00:48.980>your <00:00:49.100>room <00:00:49.339>upside <00:00:49.609>down - 00:49
stare at your room upside down

start <00:00:50.329>to <00:00:50.390>look <00:00:50.449>different - 00:50
things start to look different
- 00:51
things start to look different you<00:00:51.289>
may <00:00:51.410>even <00:00:51.559>wonder <00:00:52.010>if <00:00:52.160>you're - 00:52
you may even wonder if you're
- 00:52
you may even wonder if you're still<00:00:52.519>
in <00:00:52.879>your <00:00:52.969>bedroom <00:00:53.359> and <00:00:54.079>then - 00:54
