Long Multiplication: 850 × 8
What is 850 × 8?
Answer
850 × 8 and 8 × 850 are the same product — the order of the factors never changes the answer, only the working. Below, 850 is multiplied by 8 in a column, digit by digit.
850 × 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.
| 8 | 5 | 0 | ||
| × | 8 | |||
| 6 | 8 | 0 | 0 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 850 × 8 = 6,800.
- 0 × 8 = 0. Write 0.
- 5 × 8 = 40. Write 0 and carry 4.
- 8 × 8 = 64, plus the carried 4 makes 68. Write 8 and carry 6.
- No digits are left, so the carried 6 is written in front: the partial product is 6,800.
850 × 8
=6,800
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 6,800 ÷ 8 = 850 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.
850 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 6,800 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
