# Simplification & Approximation: VBODMAS’ Rule, Important Formula and Tricks with Problem (Question) and Solutions

Simplification is a process of reducing a complex expression into a simpler form.

### VBODMAS’ Rule

If there are more than one operation in an expression simultaneously, we have to follow a rule to solve them in a proper sequence. This rule is known as VBODMAS’ rule.

This is as follows:- Top to Bottom

V – Vinculum or Bar (‘-‘)

B – Bracket

O – of

D – Division

M – Multiplication

S – Subtraction

If any operation is not present in an expression, then we will follow the sequence by skipping that particular operation. There are three types of brackets such as

Order of solving:-

Square Bracket [ ]

Curly Bracket { }

Circular Bracket ( )

### Approximation

To find the approximate value of any expression, We use same near by values so that problem can be solved easily.
The result is also near by the correct answer.
In solving this type of problems always think about options also.
