I'm sorry I really just wanted to come on here to learn how to animate. I have never used khan academy until now and I'm not the best in math. I just want to know if I can still continue learning to animate without having to know all the math behind it.

You do not need any of this to learn how to animate, you can get very far knowing none of it. Source: I work in the games industry

i'm 8+ am i to young to understand

NO! noones too "young" to understand it (yes noone is a real word, it means no one.)

I don't get it and their so many numbers

It's called the 'Mathematics of animation curves,' so if you need to review, you should

i did slope in school before and i already know about the formula but this is hard and doesn't make any sense, doesn't explain ANYTHING that i get.

It helps you figure out where the ball is at that time, luckily, you don't always have to use this way of animating. There are some, where you just draw different frames, but you have to draw them.

First we'll use the slope intercept form of a line to define each frame along a straight line.

isn't a video just the computer animating itself?

Video transcript

- So, we've seen two ways to calculate in-betweens: linear interpolation and Bézier curves. Now let's get into the math behind them. We're gonna build on some of what we learned in the environment modeling lesson, so if you need to review, click on this link. Let's start with the simpler version, linear interpolation. Let's focus on this segment. We know the value of y at frame 4 is 750 and the value at frame 8 is 190, but what's the value of y at frame 5, 6, or 7? The picture tells us that y can be represented as a linear function of x, where x is the frame number. Linear functions can be written in slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept. Now we don't know the slope and intercept directly, but we do have two points on the line, which is enough information to calculate them. Now, once we have m and b, we can figure out y for any frame. Try out this next exercise to test your understanding of linear interpolation using the slope-intercept form.
