Okay, neat, thank you! Addition is sort of like addition, as is multiplication, and subtraction. Is division sort of like addition? And, functions seem like they're not sort of like addition - `sin(cos(x)) ?= cos(sin(x))`, or `log(cos(x)) ?= cos(log(x))` (I honestly don't remember that trig)

Sin and cos are unary operators, they don't take two inputs which is a requirement. See the parent's point #3.

Division doesn't count because (1/2)/3 = 1/6, but 1/(2/3) = 3/2. And subtraction doesn't count because 0-(1-2) != (0-1)-2.
