    What is 900 × 8?

    Answer

    900 × 8 =
    7,200

    900 × 8 and 8 × 900 are the same product — the order of the factors never changes the answer, only the working. Below, 900 is multiplied by 8 in a column, digit by digit.

    900 × 8 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.

      900
    ×   8
     7200
    900 × 8 = 7,200

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 8: 900 × 8 = 7,200.

    • 0 × 8 = 0. Write 0.
    • 0 × 8 = 0. Write 0.
    • 9 × 8 = 72. Write 2 and carry 7.
    • No digits are left, so the carried 7 is written in front: the partial product is 7,200.

    900 × 8

    =

    7,200

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 7,200 ÷ 8 = 900 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.

    900 × 8 is a number, not an area. If those are the sides of a room in feet, the answer is 7,200 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 900 × 8? (The answer is: 7,200). Enter the multiplicand (e.g. '900') and the multiplier (e.g. '8') and hit the button. The order of the two numbers does not matter — 900 × 8 and 8 × 900 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.

    FAQ

    What is 900 × 8?

    900 × 8 = 7,200

    Is 900 × 8 the same as 8 × 900?

    Yes. Multiplication is commutative, so both come to 7,200. Only the working differs: this page multiplies by 8, which gives a single partial product.

    How do you check that 900 × 8 = 7,200?

    Divide the product back by one of the factors: 7,200 ÷ 8 = 900 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 900 × 8?

    There is only one: the multiplier 8 has a single digit, so 900 × 8 = 7,200 is written straight under the line, with no addition step.
