From addition to multiplication? - David - 04-15-2014
Is there a way to write a+b without using addition? I mean something like
"a \cdot \frac{a+b}{a}" (Use dis: click).
But there still is an addition sign in there. I'm not sure if you think I'm nuts or something but I was bored, like, reaaaaaaally bored and I just wondered that.
Also, not sure if this is the right subforum, but this seemed like the most logical place. Y'know, math and all.

Yeah dummy, do this A-(-B)
Theres your addition!!!

Well, no shit. I was really looking for multiplication.

so a multiplication program would use shift and subtract negative, which is the same as shift and add.

Yeah, true. But I'm wondering if you can do it without addition or subtraction.

Hehe :p I don't THINK it's possible, (unless you wanted to define other operators or use matrices or what-not), but... maybe I'm wrong.

Yeah, I don't think it's possible either. But I could always give it a shot.

im sure you could use some trickery with factorials to get it to work
