Long Multiplication: 47 × 7

What is 47 × 7?
Answer
47 × 7 and 7 × 47 are the same product — the order of the factors never changes the answer, only the working. Below, 47 is multiplied by 7 in a column, digit by digit.
47 × 7 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.

| 3 | 2 | 9 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 47 × 7 = 329.
- 7 × 7 = 49. Write 9 and carry 4.
- 4 × 7 = 28, plus the carried 4 makes 32. Write 2 and carry 3.
- No digits are left, so the carried 3 is written in front: the partial product is 329.

Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 329 ÷ 7 = 47 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.
47 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 329 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
