Question

Simplify the following expression:

$\left\{3\times (7+18)÷(2+13)\right\}-4$

Answer 1

$\left\{3\times (7+18)÷(2+13)\right\}-4$

$$\begin{gathered} =\left\{3\times 25÷15\right\}-4 \\ =\left\{3\times \frac{25}{15}\right\}-4 \\ =5-4 \\ =1 \end{gathered}$$ ( By BODMAS rule )

Hence,$1$ is the correct answer.
