## Simplification

Simplification – General Questions Practice different types of aptitude test for free, including numerical and verbal tests. All questions come with worked solutions to help you improve.

### What is simplification method?

Mathematics. Simplification isÂ **the process of replacing a mathematical expression by an equivalent one, that is simpler**Â (usually shorter), for example. Simplifications of fractions.

### What is simplification in aptitude?

Simplification is based on basic math calculations and some other algebraic topics. And Simplification is less time consuming and having higher accuracy. Simplification isÂ **converting or finding the missing values from the long and complex expressions using the basic**Â BODMAS rules.

### BODMAS- Basic concepts

Learn the important concepts and tricks to solve questions based on Simplification.

### Important Formulas –

### BODMAS:

Though this area may have less of direct questions appearing in most of the competitive exams, but its indirect application makes this topic very relevant from the Quant section point of view. Simplification or simplify fractions means to simplify a complicated mathematical expression to get a single or direct answer.

BODMAS rule | |

B | Bracket (Brackets are solved in order of (), {} and [] respectively. |

O | Of Ãž multiplication, but it is to be done before division. |

D | Division |

M | Multiplication |

A | Addition |

S | Subtraction |

*‘BODMAS’ Rule:*This rule depicts the correct sequence in which the operations are to be executed, so as to find out the value of given expression.Here B – Bracket,

O – of,

D – Division,

M – Multiplication,

A – Addition and

S – SubtractionThus, 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:(i) of (ii) Division (iii) Multiplication (iv) Addition (v) Subtraction.*Modulus of a Real Number:*Modulus of a real numberÂ*a*Â is defined as- |
*a*| =*a*, ifÂ*a*Â > 0 *a*| =-*a*, ifÂ*a*Â < 0 Thus, |5| = 5 and |-5| = -(-5) = 5.

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