Let's evaluate the expression \( a - b - c \) given that:

- \( a = -8 \)
- \( b = -3 \)
- \( c = 10 \)

### Step-by-Step Solution:

1. Start by substituting the values of \( a \), \( b \), and \( c \) into the expression:
   \[
   (-8) - (-3) - 10
   \]

2. Simplify the subtraction of a negative number:
   \[
   (-8) + 3 - 10
   \]

3. Perform the addition and subtraction from left to right:
   \[
   -8 + 3 = -5
   \]
   \[
   -5 - 10 = -15
   \]

Thus, the result of the expression \( a - b - c \) is \( \boxed{-15} \).
