    640 × 5 in a column

    640
    ×5
    3200

    In the column: product 3,200.

    Step by step: 640 × 5

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 640 × 5 = 3,200.
      • 0 × 5 = 0. Write 0.
      • 4 × 5 = 20. Write 0 and carry 2.
      • 6 × 5 = 30, plus the carried 2 makes 32. Write 2 and carry 3.
      • No digits are left, so the carried 3 is written in front: the partial product is 3,200.
