Explanation

To solve the expression \(-15 - 27 - 88 - 63 + 255\), we will follow these steps:

### Step 1: Combine the negative numbers
First, we will add all the negative numbers together:
\[ -15 - 27 - 88 - 63 \]
Calculating this step-by-step:
- Combine \(-15\) and \(-27\):
\[ -15 - 27 = -42 \]
- Now, combine \(-42\) with \(-88\):
\[ -42 - 88 = -130 \]
- Finally, combine \(-130\) with \(-63\):
\[ -130 - 63 = -193 \]

### Step 2: Add the positive number
Now we will add \(255\) to \(-193\):
\[ -193 + 255 \]
To do this, we can think of it as:
\[ 255 - 193 \]
Calculating this:
\[ 255 - 193 = 62 \]

### Step 3: Determine the sign
Since \(255\) is greater than \(193\), the result is positive. Therefore, the final answer is:
\[ 62 \]

### Final Answer:
\[ -15 - 27 - 88 - 63 + 255 = 62 \]
