You just touch the screen a lot
I love this! * Vectors are super cool. I love that programming and Scratch make them so useful. In school, they are very boring. Also, I was bad at Physics... But I really like Geometry. Unfortunately, all of this involves Calculus. * Does the explanation help? It's actually really simple. What I mean is, a lot of other proofs are seriously horrible. But I think that it's really important to understand this one since vector components come up literally everywhere it is like fundamental.
