What is 30 × 20?

Answer

30 × 20 =
600

One partial product: the only non-zero digit of 20 is 2, and it stands for 2 × 10: 30 × 20 = 600. 20 × 30 gives the same 600.

Step by step: 30 × 20

  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 2, and it stands for 20: 30 × 20 = 600.
    • 0 × 2 = 0. Write 0.

FAQ

What is 30 × 20?

30 × 20 = 600

Is 30 × 20 the same as 20 × 30?

Yes. Multiplication is commutative, so both come to 600. Only the working differs: this page multiplies by 20, which gives a single partial product.

How do you check that 30 × 20 = 600?

Divide the product back by one of the factors: 600 ÷ 20 = 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 × 20?

Only one of them counts: every other digit of 20 is a zero and contributes nothing, so the work comes down to 30 × 20 = 600, with nothing left to add.
