Q 1: How does Bodmas rule work?

Ans: It explains the order of operations to solve an expression. According to Bodmas rule, if an expression consists of brackets ((), {}, []) we must first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

The order of operations is as follows: 1) simplify terms inside parentheses or brackets, 2) simplify exponents and roots, 3) perform multiplication and division, 4) perform addition and subtraction. Division and multiplications are both given equal priority, as are addition and subtraction. Solving the given solution in the wrong method or order shall result in the wrong answer ultimately.

• If a specific number of figures are provided, we can make complex numbers having the related number of digits by interchanging positions of those digits.
