    ×9
    135

    In the column: product 135.

    Step by step: 15 × 9

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 9: 15 × 9 = 135.
      • 5 × 9 = 45. Write 5 and carry 4.
      • 1 × 9 = 9, plus the carried 4 makes 13. Write 3 and carry 1.
      • No digits are left, so the carried 1 is written in front: the partial product is 135.

    FAQ

    What is 15 × 9?

    15 × 9 = 135

    Is 15 × 9 the same as 9 × 15?

    Yes. Multiplication is commutative, so both come to 135. Only the working differs: this page multiplies by 9, which gives a single partial product.

    How do you check that 15 × 9 = 135?

    Divide the product back by one of the factors: 135 ÷ 9 = 15 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 15 × 9?

    There is only one: the multiplier 9 has a single digit, so 15 × 9 = 135 is written straight under the line, with no addition step.
