    FAQ

    What is 10 × 9?

    10 × 9 = 90

    Is 10 × 9 the same as 9 × 10?

    Yes. Multiplication is commutative, so both come to 90. Only the working differs: this page multiplies by 9, which gives a single partial product.

    How do you check that 10 × 9 = 90?

    Divide the product back by one of the factors: 90 ÷ 9 = 10 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 10 × 9?
