Answer 2

• As per the data given in the question, we have to find the value of the expression.

           Given data:- $(20)-(30-40).$.

           To find:- The value of the expression.

           Solution:-

• To solve the above equation we will follow the BODMAS rule.
• It is the rule used to remember the order of operations to be followed while solving expressions in mathematics.

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

Therefore by applying the BODMAS rule ,

          $(20)-(30-40)\\=(20)-(-10)\\=30.$

 Hence we will get the value of 30.
