For exponents, however, the story gets more complicated. For multiplication, it's still pretty simple: it's division. Lucky for us, mathematics, and the whole world of science, other curious people found the answer.įor addition, it was easy: the inverse operation is subtraction. In this case, they wondered if there was a way to invert all these operations. However, there is always that one curious person who asks the wildest questions. Then, an obvious question appeared: how could we write multiplying the same number several times? And again, there came some smart mathematician who introduced exponents. As soon as humanity learned to add numbers, it found a way to simplify the notation for adding the same number several times: multiplication.
