MathBot Answer:

13−2−5+−4−(5+6+7−8+1)−6=−1513 - 2 - 5 + -4 - \left(5 + 6 + 7 - 8 + 1\right) - 6 = -15

13−2−5+−4−(5+6+7−8+1)−6=11−5+−4−(5+6+7−8+1)−6=6+−4−(5+6+7−8+1)−6=6+−4−(11+7−8+1)−6=6+−4−(11+−1+1)−6=6+−4−(11+0)−6=6+−4−11−6=6+−15−6=6+−21=−15\begin{aligned}13 - 2 - 5 + -4 - \left(5 + 6 + 7 - 8 + 1\right) - 6&=11 - 5 + -4 - \left(5 + 6 + 7 - 8 + 1\right) - 6\\&=6 + -4 - \left(5 + 6 + 7 - 8 + 1\right) - 6\\&=6 + -4 - \left(11 + 7 - 8 + 1\right) - 6\\&=6 + -4 - \left(11 + -1 + 1\right) - 6\\&=6 + -4 - \left(11 + 0\right) - 6\\&=6 + -4 - 11 - 6\\&=6 + -15 - 6\\&=6 + -21\\&=-15\end{aligned}
