Fibonacci numbers

Today I was on Youtube and I was watching a video on Fibonacci numbers, I just love Fibonacci numbers and I just love math, also. Fibonacci numbers work like this - you start with 0 but 0 does not equal anything. Then you do 1, but when you add 0 and 1 it still will be 1.  Then you do another 1 and you add 1 and 1, so 1+1=2, then you do the last numbers, so 1+2=3 then 2+3=5 then 3+5=8 and so on.

It should look like this: 0,1,1,2,3,5,8,13,21,34,55,89,144and so on

There's 3 parts of the video:
