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) = 74. 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.
