    FAQ

    What is 100 × 4?

    100 × 4 = 400

    Is 100 × 4 the same as 4 × 100?

    Yes. Multiplication is commutative, so both come to 400. Only the working differs: this page multiplies by 4, which gives a single partial product.

    How do you check that 100 × 4 = 400?

    Divide the product back by one of the factors: 400 ÷ 4 = 100 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 100 × 4?

    There is only one: the multiplier 4 has a single digit, so 100 × 4 = 400 is written straight under the line, with no addition step.
