GAMES ON MATH : BODMAS

 BODMAS:

 As per the BODMAS rule, we have to calculate the expressions given in the brackets first. 

The full form of BODMAS is Brackets, Orders, Division, Multiplication, Addition and Subtraction. 

Hence, the second preference in BODMAS is given here to the orders or exponents (xn). 

 Later we perform the arithmetic operations (÷, ×, +, -). 

We will solve examples based on this rule in the below sections.

It explains the order of operations to be performed while solving an expression. 

According to the BODMAS rule, if an expression contains brackets ((), {}, []) we have first to solve or simplify the bracket followed by ‘order’ (that means powers and roots, etc.), then division, multiplication, addition and subtraction from left to right. 

Solving the problem in the wrong order will result in a wrong answer.

Tips to Remember BODMAS Rule:

The rules to simplify the expression using BODMAS rule are as follows:

• First, simplify the brackets
• Solve the exponent or root terms
• Perform division or multiplication operation (from left to right)
• Perform addition or subtraction operation (from left to right)

Note: The “O” in the BODMAS full form is also called “Order”, which refers to the numbers which involve powers, square roots, etc. Check the examples below to have a better understanding of using the BODMAS rule.

		Example 1	Example 2
B	Brackets	5 × ( 7 – 3) = 5 × 4 = 20	24 ÷ ( 8 – 5 ) = 24 ÷ 3 = 8
O	Orders	7 + 22 = 7 + 4 = 11	10 – 32 = 10 – 9 = 1
D	Divide	9 + 12 ÷ 3 = 9 + 4 = 13	10 – 6 ÷ 2 = 10 – 3 = 7
M	Multiply	10 ÷ 2× 3 = 10 + 6 = 16	9 – 4 × 2 = 9 – 8 = 1
A	Add	4 × 3 + 5 = 12 + 5 = 17	2 × 7 + 8 = 14 + 8 = 22
S	Subtract	10 ÷ 2 – 2 = 5 – 2 = 3	9 ÷ 3 – 1 = 3 – 1 = 2
