Question

Simplify the following mathematical expression.

$\left(12+3\times 2\right)-\left(16-5\times 2\right)$

Answer 1

Step 1 : Solve the first bracket using BODMAS rule.

$$\begin{gathered} =\left(12+3\times 2\right)-\left(16-5\times 2\right) \\ =\left(12+6\right)-\left(16-5\times 2\right) \\ =\left(18\right)-\left(16-5\times 2\right) \end{gathered}$$

Step 2 : Now solve the second bracket using BODMAS rule.

$$\begin{gathered} =\left(18\right)-\left(16-10\right) \\ =\left(18\right)-\left(6\right) \end{gathered}$$

Step 3 : Subtract the remaining numbers

$=12$

Hence the result is $12$
