Basic Arithmetic Operations

Addition: finding the sum of two or more numbers. Used in calculating total revenue, costs, and profits.
Subtraction: finding the difference between two numbers. Used in calculating profit margins, inventory changes, and comparing costs.
Multiplication: finding the product of two or more numbers. Used in calculating total sales, discounts, and areas.
Division: finding the quotient of two numbers. Used in calculating unit costs, profit per unit, and ratios.

Percentages

A percentage represents a fraction of 100. Used in calculating discounts, markups, interest rates, and various proportions.
Calculating a percentage of a number: (part/whole) * 100
Finding a percentage increase or decrease: [(new value - original value)/original value] * 100

Ratios and Proportions

Ratios compare two quantities. Used in analyzing relationships between different aspects of a business, like return on investment (ROI).
Proportions show that two ratios are equal. Used in solving problems involving scaling, ingredient recipes, and similar situations.

Decimals and Fractions

Decimals represent fractional values using a decimal point. Used in calculating precise figures like financial transactions and measurements.
Fractions represent parts of a whole. Used in representing parts of totals, like market shares or ratios.
Conversions between decimals and fractions are vital for accurate calculations.

Financial Statements

Income Statement: summarizes a company's revenues and expenses over a period.
Balance Sheet: shows a company's assets, liabilities, and equity at a specific point in time.
Cash Flow Statement: tracks the movement of cash into and out of a company.

Budgeting

Creating a budget involves forecasting revenues and expenses. Different types of budgets include operating budgets, capital budgets, and sales budgets.
Variance analysis: comparing the actual results to the planned budget to identify areas of overspending or underspending.

Compound Interest

Compound interest is interest calculated on both the principal amount and the accumulated interest from previous periods. It is crucial in understanding investments and loans over extended periods.
Calculating compound interest requires understanding the formula or using financial calculators.

Depreciation

Depreciation is the decrease in value of an asset over time.
Several methods exist including straight-line, declining balance, and sum-of-the-years' digits.
Understanding depreciation is essential for accurate financial reporting and tax purposes.

Markup and Markdown

Markup is the amount added to the cost of a product to determine the selling price.
Markdown is the amount that a price is reduced. These are often expressed as percentage values.
Calculates the original price given sales price and markup/markdown.

Simple Interest

Simple interest is interest calculated only on the principal amount. It is less complex than compound interest.
Used in short-term loans and calculations without the need for compounding periods.
Calculating simple interest requires the principal, interest rate, and time.

Discounting

Discounting is reducing a price in order to incentivize transactions.
Can be categorized by whether it is a fixed amount or a percentage of the price.
Calculations incorporate a discount rate.

Markup and Markdown

Markup: adding a percentage to the original cost of an item.
Markdown: reducing the original selling price by a percentage.
Both processes lead to a final selling price.

Break-Even Analysis

Identifies the point where total revenues equal total costs.
Crucial for pricing decisions and determining the minimum sales needed to profit.

Cost-Volume-Profit (CVP) Analysis

Examines the interplay between costs, volume, and profit.
Uses information from cost data, sales volumes, and desired profits to determine sales needed for break even.

Metric Conversions

Converting quantities between different units. (e.g., pounds to kilograms, dollars to euros, miles to kilometers)
Necessary for international business dealings and standardized measurements.
