Blackpower is composed of Saltpeter, charcoal, and sulfur. Where and how did the american pioneers find sulfur? There are not to many volcanoes in the midwest!? I understand they could have made their own charcoal from wood, but where in the heck would have they gotten saltpeter and sulfur from?

N - N = 2

What do you call the "N"? I know the answer is called sum. I know in multiplication, it is:

Factor X Factor = product
And in division:

Dividend divided into Divisor = Quotient

And in addition:

Addend + Addend = sum

So what is the "Addend" "Factor" or "Dividend/Divisor" in subtraction?
