    One partial product: 80 × 5 = 400. 5 × 80 gives the same 400.

    80 × 5 in a column

    80
    ×5
    400

    In the column: product 400.

    Step by step: 80 × 5

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 80 × 5 = 400.
      • 0 × 5 = 0. Write 0.
      • 8 × 5 = 40. Write 0 and carry 4.
      • No digits are left, so the carried 4 is written in front: the partial product is 400.

    FAQ

    What is 80 × 5?

    80 × 5 = 400

    Is 80 × 5 the same as 5 × 80?

    Yes. Multiplication is commutative, so both come to 400. Only the working differs: this page multiplies by 5, which gives a single partial product.

    How do you check that 80 × 5 = 400?

    Divide the product back by one of the factors: 400 ÷ 5 = 80 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 80 × 5?

    There is only one: the multiplier 5 has a single digit, so 80 × 5 = 400 is written straight under the line, with no addition step.
