Aptitude ➤ Simplifications

Here, ‘B’ stands for 'bracket' ,

'O'for ‘of’ ,

‘D’ for 'division'

‘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.

|a| = { a, if a > 0;

|a| = { -a, if a < 0;

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