Order of Operation

How do we solve questions involving mathematical operations involving addition, subtraction, multiplication and division? The answer to this question is that we follow a particular order to solve the problem. This forms the basis to solve any kind of question.

The order is known as VBODMAS.

VBODMAS:  – It stands for (Vinculum- Bracket – Of –Division –Multiplication – Addition – Subtraction). This is an extended version of BODMAS.

V stands for vinculum or Bar (Bar which is used to show recurring numbers for e.g. ) .

B stands for Bracket for e.g. () , {} ,[]

O stands for Of

D stands for Division  [ ]

M stands for Multiplication [X]

A stands for Addition [+]

S stands for subtraction [-]

Let us see some examples based on this.

Example 1:

What is the value of N=4+5-7?

Solution:

According to BODMAS, first addition should take place and then subtraction.

So, N =(4+5) -7 = 9-7 = 2

Example 2:

What is the value of N= {(4 +5) of4}/3 + 2?

Solution:

We will first solve the bracket, N = {(9) x 4}/3 + 2 = 12 + 2 = 14.

Let’s try out some more questions.
