Question

Solve: $45+3\{34-18-14\}÷3\{17+3\times 4-(2\times 7\left)\right]$

Answer 1

$45+3[34-18-14]÷3[17+3\times 4-(2\times 7\left)\right]$

$\Rightarrow 45+3[34-32]÷3[17+12-14]$

$\Rightarrow 45+\frac{3\times 2}{3\times 15}$

$\Rightarrow 45+\frac{2}{15}$

$\Rightarrow \frac{675+2}{15}=\frac{677}{15}$ Ans
