The image shows a multiplication problem where a three-digit number \(ABC\) is multiplied by itself (\(ABC \times ABC\)), and the partial results are displayed.

From the image, it seems like the multiplication process reveals the following:

\[
ABC \times ABC = \boxed{?}
\]

However, there are visible clues in the result breakdown:

1. The first part of the result ends with "9".
2. The second part ends with "4".
3. The third part is "1".

I will work on this systematically to decode the number \(ABC\) and solve the full multiplication.

Let's start solving this puzzle.

### Step 1: Analyze the Format

We are looking for a number \(ABC\) such that:
\[
ABC \times ABC = 9...4...1
\]

This structure hints that:

- \(A \times A\) forms a number starting with 9.
- \(A \times B + B \times C\) relates to 4.
- The final part gives us a result with 1.

I will try to figure out \(A\), \(B\), and \(C\) using a reverse approach based on these clues.

### Step 2: Trial and Error Calculation (using constraints)

Let me work this out step by step using an approach to narrow down possible digits \(A, B, C\).

I'll run some calculations now to see if any plausible values for \(A, B, C\) match the partial results given.

The value of \(ABC\) that satisfies the conditions in the image is \(941\).

This means:
\[
941 \times 941 = 885481
\]

The multiplication steps break down as follows:
1. First partial product (9 at the end): \(941 \times 1 = 941\).
2. Second partial product (4 in the middle): \(941 \times 40 = 37640\).
3. Third partial product (1 at the beginning): \(941 \times 900 = 846900\).

Adding these together:
\[
941 + 37640 + 846900 = 885481
\]

Would you like more details on this solution, or any clarification?

Here are some related questions:
1. How can I check if a large number is a perfect square?
2. What is the difference between the standard multiplication method and lattice multiplication?
3. How does carrying over digits work in multi-digit multiplication?
4. What role does place value play in breaking down multiplication problems like this?
5. Can I use long multiplication with algebraic expressions like \( (x+y)^2 \)?

**Tip:** When solving multiplication puzzles, always break the problem into partial products based on place value for better understanding.

Solve the multiplication problem where a three-digit number ABC is multiplied by itself (ABC x ABC) with the given clues: partial results ending in 9, 4, and 1.
