## Study Notes

### Order of Operations

• The order of operations is a standardized sequence for performing mathematical calculations.
• Ensures consistent solutions when solving equations.
• Adheres to the acronym PEMDAS for determining the sequence of operations.

### PEMDAS Breakdown

• P: Parentheses – Solve expressions within parentheses first.
• E: Exponents – Calculate powers and roots next.
• MD: Multiplication and Division – From left to right as they appear.
• AS: Addition and Subtraction – From left to right as they appear.

### Example Calculation

• Expression: 12 * 6 + (18 + 9°4)
• Result: 6,651 after applying order of operations correctly.

### Additional Example Calculation

• Expression: 18 + 23 * 66
• Result: 318, demonstrating multiplication before addition.

### Algebraic Expression Representation

• Marino's financial situation can be represented as X + 15, where X is Kaitlyn's amount.
• This forms the basis for comparative equations in problems.

### Eileen's Purchase Calculation

• Represents Eileen's flower purchase with the expression (X × 5) + 12, where X is the cost of each rose.
• Incorporates both multiplication for the roses and a fixed cost for the daisy.
