What is 90 × 25?

Answer

90 × 25 =

In the column: product 2,250.

Step by step: 90 × 25

  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 2, and it stands for 20: 90 × 20 = 1,800.
    • 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.
  3. Sum of the partial products450 + 1,800 = 2,250
