The document discusses the order of operations when solving mathematical equations. It states that operations within parentheses, brackets, and braces should be solved first. Exponents are then solved before multiplication and division from left to right, followed by addition and subtraction from left to right. Several example equations are provided to demonstrate solving for the variable N using the proper order of operations.

1. ORDER OF
OPERATIONSPrepared by: Ms. Jenny Tuazon

2. GROUPINGS
Solve first the operations inside the
parenthesis, then brackets, and braces.
( ) – Parenthesis
[ ] – Bracket
{ } – Braces

3. EXPONENTS
Solve the numbers with exponents
before doing the operations.

4. MULTIPLICATION/
DIVISION
You may multiply or divide first which
ever comes first in the equation.

5. ADDITION/
SUBTRACTION
You may add/subtract first whichever
comes first in the equation

6. EXAMPLES
1. 𝟐𝟎𝟎 − 𝟒 𝟐
÷ 𝟖 × 𝟒 = 𝑵
2. 𝟐 𝟐
+ (𝟐𝟑 × 𝟒) ÷ 𝟏𝟐 = 𝑵

8. SOLVE FOR N OF THE FOLLOWING NUMBERS.
1. 𝟕 × 𝟑 + 𝟑𝟓 = 𝑵
2. 𝟔 + 𝟐 ÷ 𝟐 = 𝑵
3. 𝟑𝟐 + 𝟐𝟏 − 𝟏𝟒 ÷ 𝟕 = 𝑵
4. 𝟏𝟐 × 𝟑 + 𝟖𝟒 ÷ 𝟒 + 𝟔 = 𝑵
5. 𝟑𝟐 + 𝟔𝟓 − 𝟐𝟗 × 𝟐 − 𝟐𝟎 = 𝑵
