What is 180 × 2?

Answer

180 × 2 =
360

180 × 2 and 2 × 180 are the same product — the order of the factors never changes the answer, only the working. Below, 180 is multiplied by 2 in a column, digit by digit.

180 × 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.

Step-by-Step Solution

Step 1: Multiply the multiplicand by the last digit of the multiplier, 2: 180 × 2 = 360.

  • 0 × 2 = 0. Write 0.
  • 8 × 2 = 16. Write 6 and carry 1.
  • 1 × 2 = 2, plus the carried 1 makes 3. Write 3.

Check It, and What It Is Not

Check by dividing back. Multiplication and division undo each other, so 360 ÷ 2 = 180 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.

180 × 2 is a number, not an area. If those are the sides of a room in feet, the answer is 360 square feet — the same arithmetic, a different question, and it is answered by the square footage calculator.

Long Multiplication Calculator

This calculator multiplies two whole numbers the way it is done on paper: digit by digit, carrying where the column overflows, then adding the partial products together. For example, it can help you find out what is 180 × 2? (The answer is: 360). Enter the multiplicand (e.g. '180') and the multiplier (e.g. '2') and hit the button. The order of the two numbers does not matter — 180 × 2 and 2 × 180 are the same product — so either number can go on top. Fractions and mixed numbers belong to the fraction multiplication calculator, and the reverse operation is long division.
