You asked:

Evaluate the expression: −6(7−12)+15(1−204)−−13-6 \left(7 - 12\right) + 15 \left(1 - \frac{20}{4}\right) - -13

MathBot Answer:

−6(7−12)+15(1−204)−−13=−17-6 \left(7 - 12\right) + 15 \left(1 - \frac{20}{4}\right) - -13 = -17

−6(7−12)+15(1−204)−−13=−6⋅−5+15(1−204)−−13=30+15(1−204)−−13=30+15(1−5)−−13=30+15⋅−4−−13=30+−60−−13=−30−−13=−17\begin{aligned}-6 \left(7 - 12\right) + 15 \left(1 - \frac{20}{4}\right) - -13&=-6 \cdot -5 + 15 \left(1 - \frac{20}{4}\right) - -13\\&=30 + 15 \left(1 - \frac{20}{4}\right) - -13\\&=30 + 15 \left(1 - 5\right) - -13\\&=30 + 15 \cdot -4 - -13\\&=30 + -60 - -13\\&=-30 - -13\\&=-17\end{aligned}
