In the column: product 1,080.

Step by step: 90 × 12

  1. Step 1Multiply the multiplicand by the last digit of the multiplier, 2: 90 × 2 = 180.
    • 0 × 2 = 0. Write 0.
    • 9 × 2 = 18. Write 8 and carry 1.
    • No digits are left, so the carried 1 is written in front: the partial product is 180.
  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 products180 + 900 = 1,080
