Multiplication and division are inverse operations. If we know 3×4=12, we can say 12÷3=4 and 12÷4=3. That helps us check our work: after multiplying, we can divide the product by one factor and get the other factor back.
Multiplication and division undo each other
3×4=12⇒12÷3=4
5×6=30⇒30÷5=6
You can use division to check multiplication
