Master fundamental arithmetic operations with comprehensive explanations and examples
Addition is the process of combining two or more numbers to find their total sum. It's the most fundamental arithmetic operation and forms the basis for all other operations.
Subtraction finds the difference between two numbers. It can be thought of as adding the opposite (negative) of a number, making it closely related to addition.
Multiplication is repeated addition. It combines equal groups to find the total. Understanding multiplication is crucial for division, fractions, and advanced mathematics.
Division splits a number into equal parts. It's the inverse operation of multiplication and is essential for finding rates, ratios, and solving equations.
When multiple operations appear in an expression, they must be performed in the correct order to get the right answer. This order is universally agreed upon in mathematics.
Percentages represent parts of a whole as fractions of 100. Our calculator handles various percentage calculations automatically.
Decimals represent fractions in base-10 notation. Understanding decimal operations is essential for precise calculations and real-world applications.
Professional calculators must handle errors gracefully and provide meaningful feedback when invalid operations are attempted.
Memory functions allow you to store, recall, and manipulate numbers during complex calculations. This feature is essential for multi-step problems and professional calculations.
