      • 5 × 3 = 15. Write 5 and carry 1.
      • 4 × 3 = 12, plus the carried 1 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 45 × 3?

    45 × 3 = 135

    Is 45 × 3 the same as 3 × 45?

    Yes. Multiplication is commutative, so both come to 135. Only the working differs: this page multiplies by 3, which gives a single partial product.

    How do you check that 45 × 3 = 135?

    Divide the product back by one of the factors: 135 ÷ 3 = 45 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 45 × 3?

    There is only one: the multiplier 3 has a single digit, so 45 × 3 = 135 is written straight under the line, with no addition step.
