You asked:

Evaluate the expression: −(23−17−(−12+15−(−2+4−8))+23)-\left( 23 - 17 - \left(-12 + 15 - \left(-2 + 4 - 8\right)\right) + 23 \right)

MathBot Answer:

−(23−17−(−12+15−(−2+4−8))+23)=−20-\left( 23 - 17 - \left(-12 + 15 - \left(-2 + 4 - 8\right)\right) + 23 \right) = -20

−(23−17−(−12+15−(−2+4−8))+23)=−(6−(−12+15−(−2+4−8))+23)=−(6−(3−(−2+4−8))+23)=−(6−(3−(2−8))+23)=−(6−(3−−6)+23)=−(6−9+23)=−(−3+23)=−20\begin{aligned}-\left( 23 - 17 - \left(-12 + 15 - \left(-2 + 4 - 8\right)\right) + 23 \right)&=-\left( 6 - \left(-12 + 15 - \left(-2 + 4 - 8\right)\right) + 23 \right)\\&=-\left( 6 - \left(3 - \left(-2 + 4 - 8\right)\right) + 23 \right)\\&=-\left( 6 - \left(3 - \left(2 - 8\right)\right) + 23 \right)\\&=-\left( 6 - \left(3 - -6\right) + 23 \right)\\&=-\left( 6 - 9 + 23 \right)\\&=-\left( -3 + 23 \right)\\&=-20\end{aligned}
