16 ÷ (2 + 6) + 18[3 + (4 × 6) − 21]
You asked:
Evaluate the expression: \(\frac{16}{2 + 6} + 18 \cdot \left(3 + 4 \cdot 6 - 21\right)\)
MathBot Answer:
\[\frac{16}{2 + 6} + 18 \cdot \left(3 + 4 \cdot 6 - 21\right) = 110\]
\[\begin{aligned}\frac{16}{2 + 6} + 18 \cdot \left(3 + 4 \cdot 6 - 21\right)& = 16 \cdot \frac{1}{2 + 6} + 18 \cdot \left(3 + 4 \cdot 6 - 21\right)\\& = \frac{16}{8} + 18 \cdot \left(3 + 4 \cdot 6 - 21\right)\\& = 2 + 18 \cdot \left(3 + 4 \cdot 6 - 21\right)\\& = 2 + 18 \cdot \left(3 + 24 - 21\right)\\& = 2 + 18 \cdot \left(27 - 21\right)\\& = 2 + 18 \cdot 6\\& = 2 + 108\\& = 110\end{aligned}\]
