00:00:00-->00:00:03
Let's go forward some more,
I don't know how much more

2
00:00:04-->00:00:08
but go forward some more um again you can use

3
00:00:09-->00:00:11
it to help you estimate how
positive is function A?

4
00:00:12-->00:00:17
It's positive, is it very
positive? Yes. Yea maybe

5
00:00:18-->00:00:20
depends on how you scaled
it but it's about, we can pinch it

6
00:00:21-->00:00:25
that much positive so you guys
on your scales on your

7
00:00:26-->00:00:32,229
graph pinch off just how positive
the a value is. What about

8
00:00:32,400-->00:00:36
the b function. It's positive.
It is also positive so how can I

9
00:00:37-->00:00:41
show with my ruler how I am going
to add this to the value of

10
00:00:42-->00:00:53
the B function? Alright Ryan,
so if that's how positive A is.

11
00:00:54-->00:00:58
So I will pinch it. Now I need
to add that to the value of B.

12
00:00:59-->00:01:05
So how so? What do I want to
do with this length to show the sum?

13
00:01:06-->00:01:20
How do you show adding with two lengths?
How next to it? Yea right

14
00:01:21-->00:01:27
on top of it so if this is how positive
my A function is and that's

15
00:01:28-->00:01:34
how positive the B function is I'm
gonna take this and add it.

16
00:01:35-->00:01:39
You can like literally stack it so
here that's maybe how positive

17
00:01:40-->00:01:45
the value of A is that's perhaps
how positive the value of B is

18
00:01:46-->00:01:52
the sum and how do you show it?
How much bigger? That on top of that.

19
00:01:53-->00:01:56
Exactly it's that much bigger
so you're stacking these magnitudes

20
00:01:57-->00:01:59
now because they're positive you're
literally stacking the lengths

21
00:02:00-->00:02:03
you're estimating so you can still
use your ruler to help you pinch

22
00:02:04-->00:02:10
so that's how positive A is, that's
how positive B is so stack it and

23
00:02:11-->00:02:14
you are actually about here.
