Ancient Egyptian mathematical system identical to modern computer binary arithmetic. Ancient Egyptian mathematical system identical to modern computer binary arithmetic Egyptian multiplication method: requires only doubling and addition, no multiplication tables Powers of two system (1, 2, 4, 8, 16...) used for all calculations

Ancient Egyptian multiplication required only doubling and addition—no multiplication tables needed. Egyptians used powers of two (1, 2, 4, 8, 16...) for all calculations. Division employed the inverse of multiplication using the same powers-of-two system. Modern computers use binary (electrical on/off) states that share a conceptual similarity to the ancient Egyptian approach of using powers of two.
