Study Notes
Key Terms in Pre-Algebra
- Variable: Represents a numerical value, typically denoted by a letter (e.g., x, y).
- Constant: A fixed value that remains unchanged, essential in equations and expressions.
- Coefficient: The numerical factor that is multiplied by a variable in an expression (e.g., in 3x, 3 is the coefficient).
- Term: A single number, variable, or a product of numbers and variables combined (e.g., 4, x, or 3xy).
- Like Terms: Terms that share the same variables raised to the same powers, allowing mathematical operations such as addition or subtraction (e.g., 2x and 5x).
- Expression: A combination of numbers, variables, and operations (e.g., 3x + 5) that does not include an equals sign.
- Equation: A statement that asserts the equality of two expressions, marked by an equals sign (e.g., 2x + 3 = 7).
- Inverse Operation: An operation that reverses the effect of another (e.g., addition vs. subtraction, or multiplication vs. division).
- Integer: Includes all whole numbers, which can be positive, negative, or zero, crucial in various mathematical calculations.
