They are inverse operations.
Operations that undo each other are called inverse operations. Division is the inverse of multiplication as it undoes the multiplication. eg 3 × 7 = 21; 21 ÷ 7 = 3. Note that there is NO inverse for multiplying by 0.
Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Because multiplication and division are inverse operations. And the reciprocal of a number is its multiplicative inverse.
Because you need to use inverse operations and the opposite of multiplication is division.
Multiplication and division are inverse operations. Addition and subtraction are inverse operations too. Basically, is 5x3=15, then 15/3=5.
Addition is the inverse operation of subtraction and multiplication is the inverse operation of division. The word inverse means "opposite".
1. subtraction 2. all mathematical operations 3. multiplication 4.division has no inverse operation
Because division and multiplication are mutually inverse operations.
Multiplication is the inverse operation to division.
I think they invented it to do bigger mathscales, and to check multiplication because they are inverse operations.
