    What is 90 × 40?

    Answer

    90 × 40 =
    3,600

    One partial product: the only non-zero digit of 40 is 4, and it stands for 4 × 10: 90 × 40 = 3,600. 40 × 90 gives the same 3,600.

    90 × 40 in a column

    90
    ×40
    3600

    In the column: product 3,600.

    Step by step: 90 × 40

    1. Step 1The last digit of the multiplier is 0, so this partial product is 0 and adds nothing to the total.
    2. Step 2The next digit of the multiplier is 4, and it stands for 40: 90 × 40 = 3,600.
      • 0 × 4 = 0. Write 0.
      • 9 × 4 = 36. Write 6 and carry 3.
      • No digits are left, so the carried 3 is written in front: the partial product is 360.
    3. Product3,600

    FAQ

    What is 90 × 40?

    90 × 40 = 3,600

    Is 90 × 40 the same as 40 × 90?

    Yes. Multiplication is commutative, so both come to 3,600. Only the working differs: this page multiplies by 40, which gives a single partial product.

    How do you check that 90 × 40 = 3,600?

    Divide the product back by one of the factors: 3,600 ÷ 40 = 90 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 90 × 40?

    Only one of them counts: every other digit of 40 is a zero and contributes nothing, so the work comes down to 90 × 40 = 3,600, with nothing left to add.
