\[ 2 - 3 + 7 + \frac{8}{2} = 10 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{2}{1}\), \(\frac{-3}{1}\), \(\frac{7}{1}\), and \(\frac{8}{2}\) is \(2\). \[ \begin{aligned} 2 - 3 + 7 + \frac{8}{2} &= \frac{2 \cdot 2}{1 \cdot 2} + \frac{-3 \cdot 2}{1 \cdot 2} + \frac{7 \cdot 2}{1 \cdot 2} + \frac{8 \cdot 1}{2 \cdot 1} \\ &= \frac{4 + -6 + 14 + 8}{2} \\ &= \frac{20}{2} \\&= 10 \end{aligned} \]
