    What is 300 × 7?

    Answer

    300 × 7 =
    2,100

    300 × 7 and 7 × 300 are the same product — the order of the factors never changes the answer, only the working. Below, 300 is multiplied by 7 in a column, digit by digit.

    300 × 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.

      300
    ×   7
     2100
    300 × 7 = 2,100

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 7: 300 × 7 = 2,100.

    • 0 × 7 = 0. Write 0.
    • 0 × 7 = 0. Write 0.
    • 3 × 7 = 21. Write 1 and carry 2.
    • No digits are left, so the carried 2 is written in front: the partial product is 2,100.

    300 × 7

    =

    2,100

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 2,100 ÷ 7 = 300 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.

    300 × 7 is a number, not an area. If those are the sides of a room in feet, the answer is 2,100 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 300 × 7? (The answer is: 2,100). Enter the multiplicand (e.g. '300') and the multiplier (e.g. '7') and hit the button. The order of the two numbers does not matter — 300 × 7 and 7 × 300 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 300 × 7?

    300 × 7 = 2,100

    Is 300 × 7 the same as 7 × 300?

    Yes. Multiplication is commutative, so both come to 2,100. Only the working differs: this page multiplies by 7, which gives a single partial product.

    How do you check that 300 × 7 = 2,100?

    Divide the product back by one of the factors: 2,100 ÷ 7 = 300 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 300 × 7?

    There is only one: the multiplier 7 has a single digit, so 300 × 7 = 2,100 is written straight under the line, with no addition step.
