    What is 180 × 9?

    Answer

    180 × 9 =
    1,620

    180 × 9 and 9 × 180 are the same product — the order of the factors never changes the answer, only the working. Below, 180 is multiplied by 9 in a column, digit by digit.

    180 × 9 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.

      180
    ×   9
     1620
    180 × 9 = 1,620

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 180 × 9 = 1,620.

    • 0 × 9 = 0. Write 0.
    • 8 × 9 = 72. Write 2 and carry 7.
    • 1 × 9 = 9, plus the carried 7 makes 16. Write 6 and carry 1.
    • No digits are left, so the carried 1 is written in front: the partial product is 1,620.

    180 × 9

    =

    1,620

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 1,620 ÷ 9 = 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 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 1,620 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 × 9? (The answer is: 1,620). Enter the multiplicand (e.g. '180') and the multiplier (e.g. '9') and hit the button. The order of the two numbers does not matter — 180 × 9 and 9 × 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.
