The Deep Dive

First, let's substitute the values of \( a \), \( b \), and \( c \) into the expression \( a - b - c \). This gives us: \( 4 - 3 - (-2) \). Now, remember that subtracting a negative number is the same as adding its absolute value. So, it simplifies to: \( 4 - 3 + 2 \). Now we just perform the arithmetic step-by-step: First, \( 4 - 3 = 1 \). Then, \( 1 + 2 = 3 \). Thus, \( a - b - c = 3 \).
