Long Multiplication: 43 × 8
What is 43 × 8?
Answer
43 × 8 and 8 × 43 are the same product — the order of the factors never changes the answer, only the working. Below, 43 is multiplied by 8 in a column, digit by digit.
43 × 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.
| 4 | 3 | ||
| × | 8 | ||
| 3 | 4 | 4 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 43 × 8 = 344.
- 3 × 8 = 24. Write 4 and carry 2.
- 4 × 8 = 32, plus the carried 2 makes 34. Write 4 and carry 3.
- No digits are left, so the carried 3 is written in front: the partial product is 344.
43 × 8
=344
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 344 ÷ 8 = 43 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.
43 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 344 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
