\[ 4 - \frac{2}{4} = \frac{7}{2} = 3.5 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{4}{1}\) and \(\frac{-2}{4}\) is \(4\). \[ \begin{aligned} 4 - \frac{2}{4} &= \frac{4 \cdot 4}{1 \cdot 4} + \frac{-2 \cdot 1}{4 \cdot 1} \\ &= \frac{16 + -2}{4} \\ &= \frac{14}{4} \\&= \frac{7}{2} \end{aligned} \]
