Long Multiplication: 36 × 9
What is 36 × 9?
Answer
36 × 9 and 9 × 36 are the same product — the order of the factors never changes the answer, only the working. Below, 36 is multiplied by 9 in a column, digit by digit.
36 × 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.

| × | 9 | ||
| 3 | 2 | 4 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 36 × 9 = 324.
- 6 × 9 = 54. Write 4 and carry 5.
- 3 × 9 = 27, plus the carried 5 makes 32. Write 2 and carry 3.
- No digits are left, so the carried 3 is written in front: the partial product is 324.
36 × 9
=324
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 324 ÷ 9 = 36 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.
36 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 324 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
