    What is 80 × 15?

    Answer

    80 × 15 =
    1,200

    2 partial products: 80 × 5 = 400 and 80 × 10 = 800. 15 × 80 gives the same 1,200.

    80 × 15 in a column

    80
    ×15
    400
    +800
    1200

    In the column: product 1,200.

    Step by step: 80 × 15

    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.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 80 × 10 = 800.
      • 0 × 1 = 0. Write 0.
      • 8 × 1 = 8. Write 8.
    3. Sum of the partial products400 + 800 = 1,200
