Long Multiplication: 500 × 9
What is 500 × 9?
Answer
500 × 9 and 9 × 500 are the same product — the order of the factors never changes the answer, only the working. Below, 500 is multiplied by 9 in a column, digit by digit.
500 × 9 in a Column
The multiplicand goes on top, the multiplier underneath, both aligned on the right. The multiplier has a single digit, so there is one partial product and the answer goes straight under the line.
| 5 | 0 | 0 | ||
| × | 9 | |||
| 4 | 5 | 0 | 0 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 500 × 9 = 4,500.
- 0 × 9 = 0. Write 0.
- 0 × 9 = 0. Write 0.
- 5 × 9 = 45. Write 5 and carry 4.
- No digits are left, so the carried 4 is written in front: the partial product is 4,500.
500 × 9
=4,500
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 4,500 ÷ 9 = 500 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.
500 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 4,500 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
