What is the right answer and how?
We can solve the above mentioned problem by using BODMAS rule. According to BODMAS rule, if an expression contains brackets ((), {}, []) we have first to solve or simplify the bracket followed by ‘order’ (that means powers and roots, etc.), then division, multiplication, addition and subtraction from left to right.
First perform multiplication
the equation becomes
Addition of the numbers
equation becomes
Hence, the answer is .
