## Sample Math Problem

### Problem
Solve the following mathematical expression:

\[ -6.3 - (-2.7) = \]

### Solution
To solve the expression \(-6.3 - (-2.7)\):

1. Recognize that subtracting a negative number is the same as adding the absolute value of that number. Therefore, \(-6.3 - (-2.7)\) is equivalent to \(-6.3 + 2.7\).

2. Perform the addition:
\[ -6.3 + 2.7 \]

3. To add a negative and a positive number, subtract the smaller number from the larger number, while keeping the sign of the larger number. Here, the larger absolute value is 6.3 with a negative sign:
\[ 6.3 - 2.7 = 3.6 \]
 Keeping the sign:
\[ -3.6 \]

Thus,
\[ -6.3 - (-2.7) = -3.6 \]
