Arithmetic Operations on Numbers Basic operations include addition (+), subtraction (-), multiplication (*), and division (/). Use floor division (//) for integer results (rounds down). Modulo (%) returns the remainder. Functions: abs(x) for absolute value, max(x, y)/min(x, y) for extrema, pow(x, y)...
