Long Multiplication: 79 × 8
What is 79 × 8?
Answer
79 × 8 and 8 × 79 are the same product — the order of the factors never changes the answer, only the working. Below, 79 is multiplied by 8 in a column, digit by digit.
79 × 8 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.
| 7 | 9 | ||
| × | 8 | ||
| 6 | 3 | 2 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 79 × 8 = 632.
- 9 × 8 = 72. Write 2 and carry 7.
- 7 × 8 = 56, plus the carried 7 makes 63. Write 3 and carry 6.
- No digits are left, so the carried 6 is written in front: the partial product is 632.
79 × 8
=632
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 632 ÷ 8 = 79 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.
79 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 632 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
