Is it possible to find the absolute value of an integer using only elementary arithmetic? Using only addition, subtraction, multiplication, division, and "remainder" (modulo), can the absolute value of any integer be calculated?
To be explicit, I am hoping to find a method that does not involve a piecewise function (i.e. branching, if, if you will.)

I think you need this: https://stackoverflow.com/questions/9772348/get-absolute-value-without-using-abs-function-nor-if-statement.
Please note that remainder is modulo, absolute is modulus, so please correct the question, because I can't suggest edit.
