    What is 40 × 16?

    Answer

    40 × 16 =
    640

    2 partial products: 40 × 6 = 240 and 40 × 10 = 400. 16 × 40 gives the same 640.

    40 × 16 in a column

    40
    ×16
    240
    +400
    640

    In the column: product 640.

    Step by step: 40 × 16

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 6: 40 × 6 = 240.
      • 0 × 6 = 0. Write 0.
      • 4 × 6 = 24. Write 4 and carry 2.
      • No digits are left, so the carried 2 is written in front: the partial product is 240.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 40 × 10 = 400.
      • 0 × 1 = 0. Write 0.
      • 4 × 1 = 4. Write 4.
    3. Sum of the partial products240 + 400 = 640
