Breuken haakjesregel (reeks 2)

Bereken

\(-\left(\frac{7}{2}\right) +\left(\frac{10}{-10}\right) +\left(\frac{7}{-11}\right)\)

\(-\left(\frac{7}{2}\right) +\left(\frac{10}{-10}\right) +\left(\frac{7}{-11}\right)\\= \frac{-7}{2}- \frac{10}{10}-\frac{7}{11}\\=\frac{-7}{2}-\frac{1}{1}-\frac{7}{11}\\=\frac{-77}{22}-\frac{22}{22}-\frac{14}{22}\\=\frac{-77-22-14}{22}\\=\frac{-113}{22}\)
