$-\frac{9}{2}+\left(-1-\left(-\frac{5}{8}+\frac{1}{4}\right)\right)\\\\-\frac{9}{2}-1-\left(-\frac{5}{8}+\frac{1}{4}\right)\\\\-\frac{9}{2}-1+\frac{3}{8}\\\\-\frac{9}{2}+\frac{3}{8}-1\\\\-\frac{1}{1}-\frac{9}{2}+\frac{3}{8}\\\\-\frac{8}{8}-\frac{36}{8}+\frac{3}{8}\\\\\frac{-8-36+3}{8}\\\\-\frac{41}{8}$
