What is 80 × 15?

Answer

80 × 15 =

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
