What is BODMAS ? - Simple Techniques

BODMAS is actually an acronym that lets you know in which order/hierarchy mathematical problems have to be solved. In other words the rule or order that we use to simplify in math is called "BODMAS" rule. 

       B -> Brackets first (Parentheses)

       O -> Of (orders: Powers and radicals) 

       D -> Division 

       M -> Multiplication 

       A -> Addition 

       S -> Subtraction

Few things to remember:

1.If you have both multiplication and division or addition and subtraction in a particular simplification, you have to do one by one in the order from left to right.

2. Division mostly comes after multiplication. As said above, you have to do one by one in the order from left to right. 

Let us see few examples so as to have a better understanding

Example 1 :   6 + 7 x 8

=  6 + 7 x 8 =  6 + 56 =  62

Multiplication Addition

Example 2 : 10² - 16 ÷ 8

=  10² - 16 ÷ 8 =  100 - 16 ÷ 8 =  100 - 2  =  98

Power Division Subtraction

Example 3 :  (25 + 11) x 2

=  (25 + 11) x 2 =  36 x 2 =  72

Parenthesis Multiplication

Example 4 :  3 + 6 x (5 + 4) ÷ 3 -7

=  3 + 6 x (5+4) ÷ 3 -7 =  3 + 6 x 9 ÷ 3 -7 =  3 + 54 ÷ 3 -7 =   3 + 18 -7 =   21 - 7 =   14
