The distributive law, assuming commutativity and other axioms, is a*(b+c) = (a*b) + (a*c). Notice how it does not matter in which order you evaluate + and * in this expression due to my use of parentheses.

PEMDAS is notation. It has no influence on the actual underlying math, only how we write it.

You're absolutely right, not sure what I was thinking.

Thanks, I've been trying to figure out how to put this and you did it concisely!
