You asked:
Evaluate the expression: \(\frac{4 + 8}{2} + \frac{18}{5 + 4}\)
MathBot Answer:
\[\frac{4 + 8}{2} + \frac{18}{5 + 4} = 8\]
\[\begin{aligned}\frac{4 + 8}{2} + \frac{18}{5 + 4}& = \left(4 + 8\right) \cdot \frac{1}{2} + 18 \cdot \frac{1}{5 + 4}\\& = \frac{12}{2} + 18 \cdot \frac{1}{5 + 4}\\& = 6 + 18 \cdot \frac{1}{5 + 4}\\& = 6 + \frac{18}{9}\\& = 6 + 2\\& = 8\end{aligned}\]
