Long Multiplication: 730 × 2
What is 730 × 2?
Answer
730 × 2 and 2 × 730 are the same product — the order of the factors never changes the answer, only the working. Below, 730 is multiplied by 2 in a column, digit by digit.
730 × 2 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 | 3 | 0 | ||

| 1 | 4 | 6 | 0 |
Step-by-Step Solution
Step 1: Multiply the multiplicand by the last digit of the multiplier, 2: 730 × 2 = 1,460.
- 0 × 2 = 0. Write 0.
- 3 × 2 = 6. Write 6.
- 7 × 2 = 14. Write 4 and carry 1.
- No digits are left, so the carried 1 is written in front: the partial product is 1,460.
730 × 2
=1,460
Check It, and What It Is Not
Check by dividing back. Multiplication and division undo each other, so 1,460 ÷ 2 = 730 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.
730 × 2 is a number, not an area. If those are the sides of a room in feet, the answer is 1,460 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.
