    What is 30 × 30?

    Answer

    30 × 30 =
    900

    One partial product: the only non-zero digit of 30 is 3, and it stands for 3 × 10: 30 × 30 = 900.

    30 × 30 in a column

    30
    ×30
    900

    In the column: product 900.

    Step by step: 30 × 30

    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 3, and it stands for 30: 30 × 30 = 900.
      • 0 × 3 = 0. Write 0.
      • 3 × 3 = 9. Write 9.
    3. Product900

    FAQ

    What is 30 × 30?

    30 × 30 = 900

    Is 900 a square number?

    Yes. 30 × 30 = 900, so 900 is the square of 30. A square is simply a number multiplied by itself, which is why both factors here are the same.

    How do you check that 30 × 30 = 900?

    Divide the product back by one of the factors: 900 ÷ 30 = 30 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

    What are the partial products of 30 × 30?

    Only one of them counts: every other digit of 30 is a zero and contributes nothing, so the work comes down to 30 × 30 = 900, with nothing left to add.
