Do you know division ?

追加: 2026-06-03

Division can be understood as the inverse operation of multiplication by asking 'what number multiplied by the divisor equals the dividend?' For example, 10 ÷ 2 = 5 because 2 × 5 = 10. This conceptual approach reveals that division and multiplication are inverse operations, and it also explains why division by zero is undefined—since no number multiplied by zero can equal a non-zero value.
