Order Of Operations

BODMAS

BODMAS is a rule which is used to simplify mathematical expressions. It makes complex calculation much easier.

Each alphabet in BODMAS indicates the steps to simply any mathematical expression.

BODMAS rules involves the operations addition, multiplication, division, subtraction etc in a particular order.

Example 1:

Simplify the mathematical expression.

(90 – 36) + 338

Example 2:

Simplify the mathematical expression.

100 `÷` 25 × 4

So, from the image in any expression,

Step 1:So, 1st we solve the operations written in brackets.

Step 2:Then, we simplify if any ‘of’ is present in the expression.

Step 3: After that, we do the division and then multiplication respectively.

Step 4: At the end we do the addition and then subtraction respectively.

Then we get the final result.

Example 1:

Simplify the expression using BODMAS Rule.

390 – 2 of (46+74) `÷` 30 × 45=?

Here we use the BODMAS rule.

The operations that are used in the mathematical expression is

By BODMAS rule we use the operation as,

Step 1: 1st we do the work on the bracket.

Step 2: 2nd we use the operation ‘of’.

Step 3: 3rd we use the operation `÷`.

Step 4: 4th we use the operation ×

Step 5: 5th we use the operation −.

So, the final answer is 30.

When to use the BODMAS rule:

• In a mathematical expression when more than one operation is present then we use the BODMAS rule.
• In BODMAS rule, we follow the sequence of certain rules that need to be followed to simplify the expression.
• This gives a proper structure to produce a unique answer for every mathematical expression.
