Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I sure this is an astonishingly dumb question, but I am new to embedded systems, so dont be too harsh.

I am taking embedded systems in final year at uni and working through some introductory tutorial sheets.

One question asks;

-If two n-bit numbers are added together, what memory size is required to hold the result?

-If two n-bit numbers are multiplied together, what memory size is required to hold the result?

-If an n-bit number is multiplied with an m-bit number, what memory size is required to hold the result?

What is an n-bit number and how does it differ to an m-bit number??? I assume they are just to variable integers, and at first I presumed they could just be any size, but I would not know how to express the answer if this were the case.
