Long Multiplication: 50 × 25
What is 50 × 25?
Answer
50 × 25 and 25 × 50 are the same product — the order of the factors never changes the answer, only the working. Below, 50 is multiplied by 25 in a column, digit by digit.
50 × 25 in a Column
The multiplicand goes on top, the multiplier underneath, both aligned on the right. Each digit of the multiplier produces its own partial product, and the partial products are added up.
| 5 | 0 | |||
| × | 2 | 5 | ||
| 2 | 5 | 0 | ||
| + | 1 | 0 | 0 | 0 |
| 1 | 2 | 5 | 0 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 5: 50 × 5 = 250.
- 0 × 5 = 0. Write 0.
- 5 × 5 = 25. Write 5 and carry 2.
- No digits are left, so the carried 2 is written in front: the partial product is 250.
Step 2: The next digit of the multiplier is 2, and it stands for 20: 50 × 20 = 1,000.
- 0 × 2 = 0. Write 0.
- 5 × 2 = 10. Write 0 and carry 1.
- No digits are left, so the carried 1 is written in front: the partial product is 100.
250 + 1,000
=1,250
Adding the partial products finishes the work: 50 × 25 = 1,250.
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 1,250 ÷ 25 = 50 must come out exactly, with no remainder.
Fractions are a different calculation. Both factors here are whole numbers; for 2/3 or 2 3/4 use the fraction multiplication calculator, which multiplies numerators and denominators separately.
50 × 25 is a number, not an area. If those are the sides of a room in feet, the answer is 1,250 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
