Mathematical Operations :-

Mathematical Operations Practice Questions section is below. Here, the four fundamental operations — addition, subtraction, multiplication and division and also statements such as less than, ‘greater than’, ‘equal to’, ‘not equal to1, etc. are represented by symbols, different from the usual ones. The questions involving these operations are set using artificial symbols. The candidate has to substitute the real signs and solve the questions accordingly, to get the answer.

                    In this type of questions, usual mathematical symbols (+-,÷, x,<,> etc.) are represented by symbols, different from the usual ones. To solve this type of questions, substitute the real signs in the given expression and then solve the expression according to the rule BODMAS.
