1. ORDER OF OPERATIONS By John Rome R. Aranas

2. MDAS
MDAS stands for
Multiplication OR
Division, and Addition
OR Subtraction

3. SOLVING USING MDAS RULE
1) Start solving the equation FROM LEFT
to RIGHT.
2) Perform ALL the Multiplication OR
Division operations from left to right,
whichever comes first.
3) Then, Perform the Addition OR
Subtraction operations from left to
right, whichever comes first.

4. EXAMPLES
67 − 29 + 8 = 𝑁
1) Here, we perform first the
MULTIPLICATION OR DIVISION
FROM LEFT TO RIGHT. There’s NO
MULTIPLICATION OR DIVISION
OPERATION, so we proceed to next
step.

5. EXAMPLES
2) Afterwards, we perform ADDITION
OR SUBTRACTION.
67 − 29 + 8 = 𝑁
38 + 8 = 𝑁
46 = 𝑁

6. EXAMPLES
1) 28 + 12 − 15 = 𝑁
40 − 15 = 𝑁
25 = 𝑁

7. EXAMPLES
2) 42 ÷ 7 × 8 = 𝑁
6 × 8 = 𝑁
48 = 𝑁

8. EXAMPLES
3) 12 × 8 ÷ 6 = 𝑁
96 ÷ 6 = 𝑁
16 = 𝑁

9. EXAMPLES
4) 5 + 8 ÷ 2 − 7 = 𝑁
5 + 4 − 7 = 𝑁
9 − 7 = 𝑁
2 = 𝑁

10. EXAMPLES
5) 62 − 33 ÷ 3 + 14 = 𝑁
62 − 11 + 14 = 𝑁
51 + 14 = 𝑁
65 = 𝑁
