Hello,

I’m trying to rewrite my programs & classes to use vectors.

vectors themselves are easy, but going about the operations in p5.js has me getting lost in the syntax.

As a simple example I make 2 vectors to create a line :

```
v1 = createVector(x,y)
v2 = createVector(u,v)
line(x,y,u,v);
```

how would I rewrite this math?

```
u = y+x*2;
v = x-y*4;
```

I feel this isn’t the most efficient way to do this, but I’m only interested in the math operations without using mag or cross.

Thanks.
