Question

Simplify:21-27÷ 3+12×(-1)
​

Answer 1

We have been asked to simplify $\tt{ 21 - 27 \div 3 + 12 \times (-1)}$ . For solving this ; we will follow the BODMAS rule which says :

B - Bodmas

O - Of

D - Division

M - Multiplication

A - Addition

S - Subtraction

All of the above must be done in the same sequence in order to get the correct answer.

Following the information above ; we will solve the given problem :

$\longrightarrow{\tt{ 21 - 27 \div 3 + 12 \times (-1)}}$

Following the BODMAS rule ; there is neither a bracket term nor an of term. So we will directly skip to Divison :

$\longrightarrow{\tt{ 21 - 9 + 12 \times (-1)}}$

After Division the process of Multiplication is followed :

$\longrightarrow{\tt{ 21 - 9 - 12}}$

Now there would be Subtraction as there is no addition term :

$\longrightarrow{\tt{ 12 - 12}}$

$\large{\boxed{\implies{\tt{ 0}}}}$
