    What is 100 × 15?

    Answer

    100 × 15 =
    1,500

    2 partial products: 100 × 5 = 500 and 100 × 10 = 1,000. 15 × 100 gives the same 1,500.

    100 × 15 in a column

    100
    ×15
    500
    +1000
    1500

    In the column: product 1,500.

    Step by step: 100 × 15

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 100 × 5 = 500.
      • 0 × 5 = 0. Write 0.
      • 0 × 5 = 0. Write 0.
      • 1 × 5 = 5. Write 5.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 100 × 10 = 1,000.
      • 0 × 1 = 0. Write 0.
      • 0 × 1 = 0. Write 0.
      • 1 × 1 = 1. Write 1.
    3. Sum of the partial products500 + 1,000 = 1,500
