Hi,

I'm not sure if this is the correct forum to post this in but the question is part of a maths assignment. The question is: What system does a computer use in order to distinguish between positive and negative numbers when it stores them in memory? (How is the number of bits changed from those used to express the namber usually?)

I don't understand to what the question is referring to, I am thinking the system is binary I can't remember reading about how it distinguishes between positive and negative numbers.

Thanks
