BODMAS

Most Bank exams have 5-10 question on Simplification problems to be solved using BODMAS. It’s easy to solve them but then at times people get confused and commit silly mistakes. So, we thought we would re-iterate the basic BODMAS rule which is used to solve these problems for all to clarify such doubts, if any.

BODMAS is basically an abbreviated form of the order in which mathematical operations need to be followed while solving the Simplification problems. The letters of BODMAS stands for:

B – Bracket

O – Of

D – Division

M – Multiplication

A – Addition

S – Subtraction

Order which should be followed in case of brackets is as follows :

–          ( )

–          { }

–          [ ]

Note: When we have 2 same mathematical operations to be performed, we should go from left to right as explained in example 2 below.

Few examples which would help clear the doubts:

1)      [(3√8 + √8 ) (8 √8 + 7√8 )] – 98 = ?    (IBPS PO 2011)

= [√8(3 +1) √8 (8 + 7)] – 98

= [4√8 × 15 × √8 ] – 98

= [60 × 8] – 98= 480 – 98 = 382

2)      15 ÷ 5 ÷ 5

= 3 ÷ 5

= 0.6
