* Simplifications are asked in the various competitive exams to check the ability of an aspirant to deal with numbers which can be in one of the following two types. + Simplify the calculation. + Find out the missing number, we have to approximate the given numbers or do the basic operations. * We must aware of Bodmas formula. According to BODMAS rule, multiplication should be after division. Given below are the details of the letters and the sequence to be followed while solving simplification or BODMAS based questions.
BODMAS rule: B - Bracket (Brackets are solved in order of (), {} and [] respectively. O - Of multiplication, but it is to be done before division. D - Division M - Multiplication A - Addition S - Subtraction * The weightage of simplifications in clerical level preliminary examinations is 10-15 questions. In officer scale – I level examinations weightage is 4 - 6 questions. In SSC tier 1 exams weightage is 1 - 2 questions.
