Let's solve each expression step by step.
-
For \( 6 - (-4) \):
- Subtracting a negative is the same as adding a positive.
- Thus, \( 6 - (-4) = 6 + 4 = 10 \).
-
For \( -8 - (-3) \):
- Again, subtracting a negative is the same as adding a positive.
- So, \( -8 - (-3) = -8 + 3 = -5 \).
Therefore, the answers are:
- \( 6 - (-4) = 10 \)
- \( -8 - (-3) = -5 \)
