    What is 100 × 80?

    Answer

    100 × 80 =
    8,000

    One partial product: the only non-zero digit of 80 is 8, and it stands for 8 × 10: 100 × 80 = 8,000. 80 × 100 gives the same 8,000.

    100 × 80 in a column

    100
    ×80
    8000

    In the column: product 8,000.

    Step by step: 100 × 80

    1. Step 1The last digit of the multiplier is 0, so this partial product is 0 and adds nothing to the total.
    2. Step 2The next digit of the multiplier is 8, and it stands for 80: 100 × 80 = 8,000.
      • 0 × 8 = 0. Write 0.
      • 0 × 8 = 0. Write 0.
      • 1 × 8 = 8. Write 8.
    3. Product8,000

    FAQ

    What is 100 × 80?

    100 × 80 = 8,000

    Is 100 × 80 the same as 80 × 100?

    Yes. Multiplication is commutative, so both come to 8,000. Only the working differs: this page multiplies by 80, which gives a single partial product.

    How do you check that 100 × 80 = 8,000?

    Divide the product back by one of the factors: 8,000 ÷ 80 = 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 × 80?

    Only one of them counts: every other digit of 80 is a zero and contributes nothing, so the work comes down to 100 × 80 = 8,000, with nothing left to add.
