Simplification Questions Answers Formulas, Tips and Tricks
- 1. BODMAS Rule- This rule depicts the correct sequence in which the operations are to be executed, so as to find out the value of given expression. 
 
 Here B - Bracket,
 O - of,
 D - Division,
 M - Multiplication,
 A - Addition and
 S - Subtraction
 
 So as per rule
 First we should remove brackets
 Second we must solve "of"
 Then, Division
 Then, Multiplication
 Then, Addition,
 Then, Subtraction
 
 Please consider them strictly in order. Very basic yet very important formula. We need it in solving variety of questions in quantitative aptitude. So please be sure you are fully aware of What is bodmas and how to implement it.

- 3. Modulus of a real number- Modulus of a real number n is defined as 
 
 \begin{aligned}
 |n| = =\begin{cases}n, & if & n > 0\\-n, & if & n > 0\end{cases}
 \end{aligned}
 
 For an example,
 |7| = 7 and |-7| = -(-7) = 7
- 4. Virnaculum or BAR- When ever any question is given which contain Virnaculum, then before applying the BODMAS rule we first simplify the expression under the virnaculum.
