BODMAS rule in mathematics illustrates the order in which simple arithmetic problems should be solved. BODMAS stands for:

  1. B: Brackets
    1. ()
    2. {}
    3. []
  2. O: Of (Power, Exponents)
  3. D: Division
  4. M: Multiplication
  5. A: Addition
  6. S: Subtraction

Let’s solve some examples to better understand BODMAS rule:


5 + 5 X 5 / 5 – 5:

  1. 1
  2. 5
  3. 25
  4. 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

  1. 0
  2. 5
  3. 8
  4. 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. 1
  2. 4
  3. 8
  4. 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

  1. 12
  2. 24
  3. 80
  4. 160

Correct answer: 4. 160

Solution:

= (4 + 4) * 20

= 8 * 20

= 160


1/2 [{-2(2 + 3) * 20}/2]

  1. 5/2
  2. -10
  3. -50
  4. 18/5

Correct answer: 3. -50
