Long Multiplication: 29 × 9
What is 29 × 9?
Answer
29 × 9 and 9 × 29 are the same product — the order of the factors never changes the answer, only the working. Below, 29 is multiplied by 9 in a column, digit by digit.
29 × 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.
| 2 | 9 | ||
| × | 9 | ||
| 2 | 6 | 1 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 29 × 9 = 261.
- 9 × 9 = 81. Write 1 and carry 8.
- 2 × 9 = 18, plus the carried 8 makes 26. Write 6 and carry 2.
- No digits are left, so the carried 2 is written in front: the partial product is 261.
29 × 9
=261
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 261 ÷ 9 = 29 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.
29 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 261 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
