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
