Question

SImplify the following :

$20÷(12-2)\times 9-2$.

Answer 1

Simplify the expression:

As we know the BODMAS rule which tells about the order in which we should solve these kind of expressions.

B stands for Bracket that means we have to solve the values which are in brackets.

O stand for OFF, Similarly D stands for Division, M stands for Multiplication, A stands for Addition and S stands for Sutraction.

These operations we should follow in sequence ie, first Bracket then Off then Division, then Addition and then Subtraction.

In given problem, we observe,

$$\begin{gathered} 20÷(12-2)\times 9-2=20÷10\times 9-2 \\ =2\times 9-2 \\ =18-2 \\ =16 \end{gathered}$$

Hence,the value of $16$
