Answer 2

To solve : $-9 + 2 + (-2 ) + 9$

Solution:-

• To solve the above equation we will follow BODMAS rule.

• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

• where,  

               $\begin{array}{l} \\B= brackets \\\mathrm{O}=\text { order of powers or rules } \\\mathrm{D}=\text { Division } \\\mathrm{M}=\text { multiplication } \\\mathrm{A}=\text { addition } \\\mathrm{S}=\text { subtraction }\end{array}$

• According to above rule we will solve.  

• $-9 + 2 + (-2 ) + 9$

         $= -9 + 2 -2 + 9\\= 0$

Hence, value of expression is $0$ .
