## No problem! Let's find the least three-digit square number together.

To find the square numbers, we need to multiply a number by itself. We can start by squaring the first few numbers until we find a three-digit square number.

Let's start with the number 1: 1 x 1 = 1. That's not a three-digit number.

Next, let's try 2: 2 x 2 = 4. Still not a three-digit number.

Let's continue with 3: 3 x 3 = 9. Still not a three-digit number.

Now, let's try 4: 4 x 4 = 16. While 16 is a two-digit number, it is not a three-digit number.

Continuing with 5: 5 x 5 = 25. Still not a three-digit number.

Let's move on to 6: 6 x 6 = 36. Still not a three-digit number.

Next, let's try 7: 7 x 7 = 49. Still not a three-digit number.

Now let's try 8: 8 x 8 = 64. Still not a three-digit number.

Finally, we will square 9: 9 x 9 = 81. That's still not a three-digit number.

So, the least three-digit square number is 100, which is 10 x 10.

Therefore, you were correct in your initial response. The least three-digit square number is 100.
