Answer 1

Answer:

(90+54)÷(9×(-2))

(144)÷(-18)

=-8

Answer 2

To solve : $[ 90 - (-54) } ]\div [12 - 3 \times (-2) ]$

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 $[ 90 - (-54) } ]\div [12 - 3 \times (-2) ]$

               $= [90 + 54 ] \div [ 12 + 6 ] \\= \frac{144}{18} \\= 8$  

Hence , correct answer is $8$.
