🧮 x86 4-Operation Assembly Calculator

A simple command-line calculator written in x86 Assembly that supports the four basic arithmetic operations: addition, subtraction, multiplication, and division.

A personal project of mine, just to explore the ways of the old and wise....and boy o' boy this was insane. Even more insane to think that there are engineers out there writing drivers on this. Hmm, need to step up by game 😤
