Explanation

To solve the expression \( 436.56 - 625.43 + 312.55 \), we will follow these steps:

### Step 1: Perform the subtraction
First, we need to subtract \( 625.43 \) from \( 436.56 \).

\[ 436.56 - 625.43 \]

To perform this subtraction, we can align the numbers by their decimal points:

```
436.56
- 625.43
```

Since \( 436.56 \) is smaller than \( 625.43 \), the result will be negative. We can calculate it as follows:

1. Borrow from the next column where necessary.
2. Calculate the difference.

After performing the subtraction, we get:

\[ 436.56 - 625.43 = -188.87 \]

### Step 2: Add \( 312.55 \) to the result
Now, we will add \( 312.55 \) to the result from Step 1.

\[ -188.87 + 312.55 \]

Aligning the numbers:

```
-188.87
+312.55
```

Since we are adding a positive number to a negative number, we will subtract the absolute values and keep the sign of the larger absolute value.

Calculating the addition:

1. Subtract \( 188.87 \) from \( 312.55 \):

\[ 312.55 - 188.87 = 123.68 \]

2. Since \( 312.55 \) is greater than \( 188.87 \), the result will be positive.

Thus, we have:

\[ -188.87 + 312.55 = 123.68 \]

### Final Answer
The final answer is:

\[ \boxed{123.68} \]
