What is 80 × 25?

Answer

80 × 25 =
2,000

2 partial products: 80 × 5 = 400 and 80 × 20 = 1,600. 25 × 80 gives the same 2,000.

In the column: product 2,000.

Step by step: 80 × 25

  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 2, and it stands for 20: 80 × 20 = 1,600.
    • 0 × 2 = 0. Write 0.
    • 8 × 2 = 16. Write 6 and carry 1.
    • No digits are left, so the carried 1 is written in front: the partial product is 160.
  3. Sum of the partial products400 + 1,600 = 2,000
