BODMAS rule in mathematics illustrates the order in which simple arithmetic problems should be solved. BODMAS stands for:
- B: Brackets
- ()
- {}
- []
- O: Of (Power, Exponents)
- D: Division
- M: Multiplication
- A: Addition
- S: Subtraction
Let’s solve some examples to better understand BODMAS rule:
5 + 5 X 5 / 5 – 5:
- 1
- 5
- 25
- 0
Correct answer: 2. 5
Using DMAS rule
Step 1 (Division): 5 + 5 X (1) – 5
Step 2 (Multiplication): 5 + 5 – 5
Step 3 (Addition): 10 – 5
Step 4 (Subtraction): 5
(10 + 8 X 5 )/ 5 – 5
- 0
- 5
- 8
- 10
Correct answer: 2. 5
Step 1: First solve inside brackets
(50)/5 – 5
Step 2: Division
10 – 5
Step 3: Subtraction
5
8/2*(2+2)
- 1
- 4
- 8
- 16
Correct answer: 4.
Step 1: Sum of numbers inside bracket 8/2*(4)
Step 2: Division 4 * (4)
Step 3: Brackets 16
(12/3 + 16/4) of 20
- 12
- 24
- 80
- 160
Correct answer: 4. 160
Solution:
= (4 + 4) * 20
= 8 * 20
= 160
1/2 [{-2(2 + 3) * 20}/2]
- 5/2
- -10
- -50
- 18/5
Correct answer: 3. -50
