What is 10 × 10?

Answer

10 × 10 =

In the column: product 100.

Step by step: 10 × 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: 10 × 10 = 100.
    • 0 × 1 = 0. Write 0.

FAQ

What is 10 × 10?

10 × 10 = 100

Is 100 a square number?

Yes. 10 × 10 = 100, so 100 is the square of 10. A square is simply a number multiplied by itself, which is why both factors here are the same.

How do you check that 10 × 10 = 100?

Divide the product back by one of the factors: 100 ÷ 10 = 10 exactly, with no remainder. Multiplication and division undo each other, which is what makes this check work.

What are the partial products of 10 × 10?

Only one of them counts: every other digit of 10 is a zero and contributes nothing, so the work comes down to 10 × 10 = 100, with nothing left to add.
