Quantitative Aptitude Free-Study Notes



A. BODMAS’ Rule : This rule depicts the correct sequence in which the operations are to be executed, so as to find out the value of a given expression. Here, ‘B’ stands for ’bracket’ ,’O’for ‘of’ , ‘D’ for’ division’ and ‘M’ for ‘multiplication’, ‘A’ for ‘addition’ and ‘S’ for ‘subtraction’.

Thus, in simplifying an expression, first of all the brackets must be removed, strictly in the order ( ), { } and [ ]. After removing the brackets, we must use the following operations strictly in the order:

(1)of (2)division (3) multiplication (4)addition (5)subtraction.

B. Modulus of a real number : Modulus of a real number a is defined as

|a| = a, if a>0 -a, if a<0

Thus, |5|=5 and |-5|=-(-5)=5.

C. Virnaculum (or bar) : When an expression contains Virnaculum, before applying the ‘BODMAS’ rule, we simplify the expression under the Virnaculum.
