BODMAS RULE:

We must remember the word BODMAS in solving sums on simplification. These letters stand for bracket, of, division, multiplication, addition and subtraction respectively.

 

B Bracket- () {} and then [ ]
O of
D Division [÷]
M Multiplication [x]
A Addition [+]
S Subtraction [-]

In simplifying an expression first of all bar must be removed. After removing the bar, the brackets must be removed, strictly in the order ( ), { }and [ ].

After removing the brackets, we must use the following operations strictly in the order: (i) of (ii) Division (iii) Multiplication (iv) Addition (v) Subtraction

    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
