What is 90 × 10?

Answer

90 × 10 =
900

One partial product: the only non-zero digit of 10 is 1, and it stands for 1 × 10: 90 × 10 = 900. 10 × 90 gives the same 900.

Step by step: 90 × 10

  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 1, and it stands for 10: 90 × 10 = 900.

FAQ

What is 90 × 10?

90 × 10 = 900

Is 90 × 10 the same as 10 × 90?

Yes. Multiplication is commutative, so both come to 900. Only the working differs: this page multiplies by 10, which gives a single partial product.

How do you check that 90 × 10 = 900?

Divide the product back by one of the factors: 900 ÷ 10 = 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 × 10?

Only one of them counts: every other digit of 10 is a zero and contributes nothing, so the work comes down to 90 × 10 = 900, with nothing left to add.
