    What is 40 × 15?

    Answer

    40 × 15 =
    600

    2 partial products: 40 × 5 = 200 and 40 × 10 = 400. 15 × 40 gives the same 600.

    40 × 15 in a column

    40
    ×15

    +400
    600

    In the column: product 600.

    Step by step: 40 × 15

    1. Step 1Multiply the multiplicand by the last digit of the multiplier, 5: 40 × 5 = 200.
      • 0 × 5 = 0. Write 0.
      • 4 × 5 = 20. Write 0 and carry 2.
      • No digits are left, so the carried 2 is written in front: the partial product is 200.
    2. Step 2The next digit of the multiplier is 1, and it stands for 10: 40 × 10 = 400.
      • 0 × 1 = 0. Write 0.
      • 4 × 1 = 4. Write 4.
    3. Sum of the partial products200 + 400 = 600

    FAQ

    What is 40 × 15?

    40 × 15 = 600

    Is 40 × 15 the same as 15 × 40?

    Yes. Multiplication is commutative, so both come to 600. Only the working differs: this page multiplies by 15, which gives 2 partial products.

    How do you check that 40 × 15 = 600?

    Divide the product back by one of the factors: 600 ÷ 15 = 40 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 40 × 15?
