    What is 680 × 9?

    Answer

    680 × 9 =
    6,120

    680 × 9 and 9 × 680 are the same product — the order of the factors never changes the answer, only the working. Below, 680 is multiplied by 9 in a column, digit by digit.

    680 × 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.

      680
    ×   9
     6120
    680 × 9 = 6,120

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 9: 680 × 9 = 6,120.

    • 0 × 9 = 0. Write 0.
    • 8 × 9 = 72. Write 2 and carry 7.
    • 6 × 9 = 54, plus the carried 7 makes 61. Write 1 and carry 6.
    • No digits are left, so the carried 6 is written in front: the partial product is 6,120.

    680 × 9

    =

    6,120

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 6,120 ÷ 9 = 680 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.

    680 × 9 is a number, not an area. If those are the sides of a room in feet, the answer is 6,120 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 680 × 9? (The answer is: 6,120). Enter the multiplicand (e.g. '680') and the multiplier (e.g. '9') and hit the button. The order of the two numbers does not matter — 680 × 9 and 9 × 680 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.
