\[ \frac{-1}{2} + 1 = \frac{1}{2} = 0.5 \]

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