Mathematical Operations Practice Questions
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.

Type 1: Problem-Solving By Substitution
In this type, you are provided with substitutes for various mathematical symbols, followed by a question involving calculation of an expression or choosing the correct/incorrect equation. The candidate is required to put in the real signs in the given equation and then solve the questions as required.
Q1: If V means ‘divided by, – means ‘multiplied by’, V means ‘minus and V means ‘plus’, which of the following will be the value of the expression 16+ 8- 4 + 2 x 4? (Bank P.O. 1995)
(a) 16 (b) 28 (c) 32 (d) 44 (e) None of these
