    What is 18 × 2?

    Answer

    18 × 2 =
    36

    18 × 2 and 2 × 18 are the same product — the order of the factors never changes the answer, only the working. Below, 18 is multiplied by 2 in a column, digit by digit.

    18 × 2 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.

     18
    × 2
     36
    18 × 2 = 36

    Step-by-Step Solution

    Step 1: Multiply the multiplicand by the last digit of the multiplier, 2: 18 × 2 = 36.

    • 8 × 2 = 16. Write 6 and carry 1.
    • 1 × 2 = 2, plus the carried 1 makes 3. Write 3.

    18 × 2

    =

    36

    Check It, and What It Is Not

    Check by dividing back. Multiplication and division undo each other, so 36 ÷ 2 = 18 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.

    18 × 2 is a number, not an area. If those are the sides of a room in feet, the answer is 36 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 18 × 2? (The answer is: 36). Enter the multiplicand (e.g. '18') and the multiplier (e.g. '2') and hit the button. The order of the two numbers does not matter — 18 × 2 and 2 × 18 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 18 × 2?

    18 × 2 = 36

    Is 18 × 2 the same as 2 × 18?

    Yes. Multiplication is commutative, so both come to 36. Only the working differs: this page multiplies by 2, which gives a single partial product.

    How do you check that 18 × 2 = 36?

    Divide the product back by one of the factors: 36 ÷ 2 = 18 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 18 × 2?

    There is only one: the multiplier 2 has a single digit, so 18 × 2 = 36 is written straight under the line, with no addition step.
