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.
