BODMAS RULE
BODMAS indicates the sequence in which more than one operation is performed in the simplification process of any mathematical problem.
Removal of brackets and solving of operation ‘of’ with operations
of DMAS is known as the BODMAS rule.
In the BODMAS rule, the of denotes the order of operation.
The chain of letters in BODMAS shows meaning of each
letter as:
Examples
1) 21 ÷ 3 + (3 × 9) × 9 + 5
Step 1: (3 × 9) = 27 21 ÷ 3 + 27 × 9 + 5
Step 2: 21 ÷ 3 = 7 7 + 27 × 9 + 5
Step 3: 27 × 9 = 243 7 + 243 + 5
Step 4: 7 + 243 = 250 250 + 5
Step 5: 250 + 5 = 255 255
2) 18 ÷ 6 × (4 – 3) + 6
Step 1: (4 – 3) = 1 18 ÷ 6 × 1 + 6
Step 2: 18 ÷ 6 = 3 3 × 1 + 6
Step 3: 3 × 1 = 3 3 + 6
Step 4: 3 + 6 = 9 9
3) 14 – 8 + 3 + 8 × (24 ÷ 8)
Step 1: (24 ÷ 8) = 3 14 – 8 + 3 + 8 × 3
Step 2: 8 × 3 = 24 14 – 8 + 3 + 24
Step 3: 14 – 8 = 6 6 + 3 + 24
Step 4: 6 + 3 = 9 9 + 24
Step 5: 9 + 24 = 33 33
4) 4 × 5 + (14 + 8) – 36 ÷ 9
Step 1: (14 + 8) = 22 4 × 5 + 22 – 36 ÷ 9
Step 2: 4 × 5 = 20 20 + 22 – 36 ÷ 9
Step 3: 36 ÷ 9 = 4 20 + 22 – 4
Step 4: 20 + 22 = 42 42 – 4
Step 5: 42 – 4 = 38 38
