To solve the expression \( -2 + 3 - (-4) \), we can follow these steps:
-
Start by simplifying the expression: \[ -2 + 3 - (-4) = -2 + 3 + 4 \]
-
Now, calculate \( -2 + 3 \): \[ -2 + 3 = 1 \]
-
Next, add \( 1 + 4 \): \[ 1 + 4 = 5 \]
Thus, the solution to the expression \( -2 + 3 - (-4) \) is \( \boxed{5} \).
