You asked:

Evaluate the expression: 160+−40−20−5160 + -40 - \frac{20}{-5}

MathBot Answer:

160+−40−20−5=124 160 + -40 - \frac{20}{-5} = 124

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of 1601\frac{160}{1}, −401\frac{-40}{1}, and −20−5\frac{-20}{-5} is 55. 160+−40−20−5=160⋅51⋅5+−40⋅51⋅5+−20⋅−1−5⋅−1=800+−200+205=6205=124 \begin{aligned} 160 + -40 - \frac{20}{-5} &= \frac{160 \cdot 5}{1 \cdot 5} + \frac{-40 \cdot 5}{1 \cdot 5} + \frac{-20 \cdot -1}{-5 \cdot -1} \\ &= \frac{800 + -200 + 20}{5} \\ &= \frac{620}{5} \\&= 124 \end{aligned}
