In the column: product 5,625.

Step by step: 75 × 75

  1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 75 × 5 = 375.
    • 5 × 5 = 25. Write 5 and carry 2.
    • 7 × 5 = 35, plus the carried 2 makes 37. Write 7 and carry 3.
    • No digits are left, so the carried 3 is written in front: the partial product is 375.
  2. Step 2The next digit of the multiplier is 7, and it stands for 70: 75 × 70 = 5,250.
    • 5 × 7 = 35. Write 5 and carry 3.
    • 7 × 7 = 49, plus the carried 3 makes 52. Write 2 and carry 5.
    • No digits are left, so the carried 5 is written in front: the partial product is 525.
  3. Sum of the partial products375 + 5,250 = 5,625
