You asked:

Evaluate the expression: \(-8 + \frac{70}{-7}\)

MathBot Answer:

\[ -8 + \frac{70}{-7} = -18 \]

The sum can be computed by rewriting each term over a common denominator, where the least common denominator of \(\frac{-8}{1}\) and \(\frac{70}{-7}\) is \(7\). \[ \begin{aligned} -8 + \frac{70}{-7} &= \frac{-8 \cdot 7}{1 \cdot 7} + \frac{70 \cdot -1}{-7 \cdot -1} \\ &= \frac{-56 + -70}{7} \\ &= \frac{-126}{7} \\&= -18 \end{aligned} \]
