I need something like this:
a + a = a
b + b = b
a + b = c
b + a = c
So the position doesn't matter. I'm kinda lost
edit: I am aware of [if] and multiple conditions, but you need to specify for each input, i want it input-independent. just checks both and outputs if the combination is right.
I'd use "+" but I'm using Symbols. The stupidest way would be a dictionary in coll and an object that converts symbols to numbers.
