Answer 2

To solve : $54 -(-78) + ( -74) - 67$

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, B= brackets

            O = order of powers or rules  

            D= Division  

            M = multiplication  

             A = addition  

             S = subtraction  

According to above rule we will solve $54 -(-78) + ( -74) - 67$  

as we know $( - ) \times (- ) = (+) \ and \ (+ ) \times ( -) = ( -)$

Therefore,  

          $= 54 + 78 - 74 - 67$

on solving we get,

          $= - 9$

Hence $- 9$ is the correct answer.
