Binary Arithmetic Basics

Binary addition follows the same rules as decimal addition, but with only two digits: 0 + 0 = 0, 0 + 1 = 1, 1 + 0 = 1, and 1 + 1 = 10 (carry the 1). Binary subtraction, multiplication, and division work similarly to their decimal counterparts. Understanding binary math is fundamental to computer science, digital electronics, and low-level programming.
