What is 100 × 30?

Answer

100 × 30 =
3,000

One partial product: the only non-zero digit of 30 is 3, and it stands for 3 × 10: 100 × 30 = 3,000. 30 × 100 gives the same 3,000.

In the column: product 3,000.

Step by step: 100 × 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: 100 × 30 = 3,000.
    • 0 × 3 = 0. Write 0.
    • 0 × 3 = 0. Write 0.
    • 1 × 3 = 3. Write 3.

FAQ

What is 100 × 30?

100 × 30 = 3,000

Is 100 × 30 the same as 30 × 100?

Yes. Multiplication is commutative, so both come to 3,000. Only the working differs: this page multiplies by 30, which gives a single partial product.

How do you check that 100 × 30 = 3,000?

Divide the product back by one of the factors: 3,000 ÷ 30 = 100 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 100 × 30?

Only one of them counts: every other digit of 30 is a zero and contributes nothing, so the work comes down to 100 × 30 = 3,000, with nothing left to add.
