38-(-7)

To solve the expression \( 38 - (-7) \), you need to remember that subtracting a negative number is the same as adding the positive version of that number.

So, the expression can be rewritten as:

\[ 38 + 7 \]

Now, add the two numbers:

\[ 38 + 7 = 45 \]

Therefore, \( 38 - (-7) = 45 \).
