Study Notes
Key Mathematical Terms and Concepts
- Equation: A mathematical sentence indicating that two expressions are equal.
- Equivalent Equations: Different equations that yield the same solution, demonstrating equality in their respective outputs.
- Inverse Operations: Operations that counteract the effect of others, such as addition and subtraction or multiplication and division.
Sets and Solutions
- Null Set: A specific type of set that contains no elements, often represented by the symbol ∅.
- Solution: A value that satisfies an equation, making it true; for instance, both y + 8 = 10 and y = 18 have equivalent solutions.
Types of Equations
- Two-Step Equation: An equation requiring two distinct operations to isolate the variable; example: 2x + 3 = 7.
Constants and Variables
- Constant: A fixed value that does not contain a variable; represents a single number.
- Coefficient: A numerical factor multiplied by a variable within an algebraic expression.
Variables
- Variable: Typically a letter symbolizing one or more unknown numbers in mathematical expressions.
Properties of Equality and Operations
- Distributive Property: A key principle allowing the distribution of multiplication over addition, articulated as a(b + c) = ab + ac.
- Multiplication Property of Equality: States that multiplying both sides of an equation by the same nonzero number maintains the equality.
- Division Property of Equality: Indicates that dividing both sides of an equation by the same nonzero number keeps the equality intact.
- Addition Property of Equality: Establishes that adding the same number to both sides of an equation preserves equality.
- Subtraction Property of Equality: Confirms that subtracting the same number from both sides of an equation results in equality.
Additional Concepts
- Reciprocal: The multiplicative inverse of a number; when multiplied with the original number, yields the product of 1.
- Inequality: A formulative statement that expresses the comparison between two quantities using symbols like <, ≤, ≥, or ≠.
