- 2. an expression in math is a phrase that combines numbers, variables (like \(x\) or \(y\))
- 5. a symbol (often a letter) or factor that represents an unknown or changeable quantity
- 8. a part of a whole or a collection of objects, written as one number over another
- 10. a specific equation or system has exactly one unique value for the variable that makes the equation true
- 11. An irrational number is a real number that cannot be expressed as a simple fraction
- 13. A rational number is any number that can be expressed as a fraction
- 14. the state of being unequal, characterized by a lack of balance, fairness, or uniformity in size, rank, or distribution
- 15. a mathematical formula where the relationship between variables is not proportional, meaning it does not form a straight line when graphed
Down
- 1. a decimal number in which a digit or block of digits repeats indefinitely
- 3. the horizontal, primary reference line in a Cartesian coordinate system, typically running left-to-right (east-west) through the origin
- 4. A terminating decimal number is a decimal with a finite (limited) number of digits after the decimal point, meaning it comes to an end rather than continuing forever
- 6. an algebraic expression where variables have a degree (exponent) of 1.
- 7. the vertical (top-to-bottom) reference line on a two-dimensional Cartesian coordinate plane, usually passing through zero and labeled with values indicating vertical position or height
- 9. no possible value for the variable(s) can make an equation or system of equations true
- 12. An equation is a mathematical statement, usually written as two expressions connected by an equals sign (\(=\))
