Quantitative Aptitude - Simplification - Formula & Concept Tutorial

  1. ‘BODMAS’ Rule

This rule depict the correct sequence in which the operations are to be executed, so as to find out the value of given expression

 

Here,

B Stand for Bracket

O Stand for Order ( Power , Square , Root )

D Stand for Division ( Left to Right )

M Stand for Multiplication ( Left to Right )

A Stand for Addition ( Left to Right )

S Stand for Substraction ( Left to Right )

 

 

Example

               23 + 11 ÷ 22 + ( 12 ÷ 4 )2 – 10 × (12 × 3 )

    • 23 + 11 ÷ 22 + (3)2 – 10 × 48      ( Solve Bracket First )
    • 23 + 11 ÷ 22 + 9 – 10 × 48          ( Then Solve Order )
    • 23 + 0.5 + 9 – 10 × 48                 ( Then Solve Division )
    • 23 + 0.5 + 9 – 480                       ( Then Solve Multiplication )
    • 23 + 0.5 + 9 – 480                     ( Then Solve Addition From Left To Right)
    • 32.5 – 480                                    ( Then Solve Substraction )
    • -447.5
