(Mathematical Operation)

Reasoning test papers
often contain questions based on mathematical operations like
arithmetic,algebra,geometry etc.Knowledge of general rules of mathematics along
with intellectual ability is required to solve these questions.Generally,the
questions are based on some formulas and mathematical symbols(+,-,*) of algebra.Questions
and mathematical symbols are defined as
BODMAS(B=Bracket,O=Of,D=Division,M=Multiplication,A=Addition,S=Subtraction).Must
solve in order.Questions based on mathematical operations are asked in two
ways.(1)Based on hypothetical mathematical method (2)Based on real mathematical
method.
