    One partial product: 80 × 4 = 320. 4 × 80 gives the same 320.

    80 × 4 in a column

    80
    ×4
    320

    In the column: product 320.

    Step by step: 80 × 4

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 4: 80 × 4 = 320.
      • 0 × 4 = 0. Write 0.
      • 8 × 4 = 32. Write 2 and carry 3.
      • No digits are left, so the carried 3 is written in front: the partial product is 320.

    FAQ

    What is 80 × 4?

    80 × 4 = 320

    Is 80 × 4 the same as 4 × 80?

    Yes. Multiplication is commutative, so both come to 320. Only the working differs: this page multiplies by 4, which gives a single partial product.

    How do you check that 80 × 4 = 320?

    Divide the product back by one of the factors: 320 ÷ 4 = 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 × 4?

    There is only one: the multiplier 4 has a single digit, so 80 × 4 = 320 is written straight under the line, with no addition step.
