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.
