    What is 90 × 15?

    Answer

    90 × 15 =
    1,350

    1350

    In the column: product 1,350.

    Step by step: 90 × 15

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 90 × 5 = 450.
      • 0 × 5 = 0. Write 0.
      • 9 × 5 = 45. Write 5 and carry 4.
      • No digits are left, so the carried 4 is written in front: the partial product is 450.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 90 × 10 = 900.
      • 0 × 1 = 0. Write 0.
      • 9 × 1 = 9. Write 9.
    3. Sum of the partial products450 + 900 = 1,350
