Long Multiplication: 22 × 7

What is 22 × 7?
Answer
22 × 7 and 7 × 22 are the same product — the order of the factors never changes the answer, only the working. Below, 22 is multiplied by 7 in a column, digit by digit.
22 × 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.

Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 22 × 7 = 154.
- 2 × 7 = 14. Write 4 and carry 1.
- 2 × 7 = 14, plus the carried 1 makes 15. Write 5 and carry 1.
- No digits are left, so the carried 1 is written in front: the partial product is 154.

Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 154 ÷ 7 = 22 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.
22 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 154 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
