Easy and simple way to remember **BODMAS **rule**!!**

B** →** **B**rackets first (parentheses)

O **→ ****O**f** **(orders i.e. Powers and Square Roots, Cube Roots, etc.)

DM **→** **D**ivision and **M**ultiplication (start from left to right)

AS **→ ****A**ddition and **S**ubtraction (start from left to right)

Note:

(i) Start Divide/Multiply from left side to right side since they perform equally.

(ii) Start Add/Subtract from left side to right side since they perform equally.

Steps to simplify the order of operation using BODMAS rule:

First part of an equation is start solving inside the 'Brackets'.

**For Example;** (6 + 4) × 5

First solve inside ‘brackets’ 6 + 4 = 10, then 10 × 5 = 50.

Next solve the mathematical 'Of'.

**For Example;** 3 of 4 + 9

First solve ‘of’ 3 × 4 = 12, then 12 + 9 = 21.

Next, the part of the equation is to calculate 'Division' and 'Multiplication'.

We know that, when division and multiplication follow one another, then their order in that part of the equation is solved from left side to right side.

**For Example;** 15 ÷ 3 × 1 ÷ 5

‘**Multiplication**’ and ‘**Division**’ perform equally, so calculate from left to right side. First solve 15 ÷ 3 = 5, then 5 × 1 = 5, then 5 ÷ 5 = 1.

In the last part of the equation is to calculate 'Addition' and 'Subtraction'. We know that, when addition and subtraction follow one another, then their order in that part of the equation is solved from left side to right side.

**For Example;** 7 + 19 - 11 + 13

‘**Addition**’ and ‘**Subtraction**’ perform equally, so calculate from left to right side. First solve 7 + 19 = 26, then 26 - 11 = 15 and then 15 + 13 = 28.

*T**hese are simple rules need to be followed for simplifying or calculatingusing BODMAS rule.*

In brief, after we perform "B" and "O", start from left side to right side by solving any "D" or "M" as we find them. Then start from left side to right side solving any "A" or "S" as we find them.
