    What is 870 × 7?

    Answer

    870 × 7 =
    6,090

    870 × 7 and 7 × 870 are the same product — the order of the factors never changes the answer, only the working. Below, 870 is multiplied by 7 in a column, digit by digit.

    870 × 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.

      870
    ×   7
     6090
    870 × 7 = 6,090

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 870 × 7 = 6,090.

    • 0 × 7 = 0. Write 0.
    • 7 × 7 = 49. Write 9 and carry 4.
    • 8 × 7 = 56, plus the carried 4 makes 60. Write 0 and carry 6.
    • No digits are left, so the carried 6 is written in front: the partial product is 6,090.

    870 × 7

    =

    6,090

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 6,090 ÷ 7 = 870 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.

    870 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 6,090 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 870 × 7? (The answer is: 6,090). Enter the multiplicand (e.g. '870') and the multiplier (e.g. '7') and hit the button. The order of the two numbers does not matter — 870 × 7 and 7 × 870 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.
