Across
- 8. A mathematical phrase containing numbers, variables, and operators (like \(+\) or \(-\)) but no equal sign (e.g., \(8x - 9y\)).
- 11. The value of a variable that makes an equation true, or the solution to a polynomial equation.
- 12. A mathematical statement asserting that two expressions are equal, featuring an equals sign (e.g., \(4x - 7 = 5\)).
- 13. Any number from the set of whole numbers and their opposites, including negative numbers, zero, and positive numbers (\(\dots, -2, -1, 0, 1, 2, \dots\)).
- 14. A number used to multiply a variable; it is the numerical part in front of a variable, such as the '4' in \(4x\).
- 15. An algebraic expression consisting of one or more terms, specifically with non-negative integer exponents (e.g., \(3x^2 - 2x + 1\)).
Down
- 1. A fixed value that does not change, usually a number on its own (e.g., in \(4x + 3\), 3 is the constant).
- 2. A polynomial expression with exactly two unlike terms, such as \(4a^2 + 3b\).
- 3. A number or expression that divides another number or expression exactly.
- 4. A single number, a variable, or numbers and variables multiplied together, separated by \(+\) or \(-\) signs.
- 5. The intersection point of the \(x\)-axis and \(y\)-axis on a coordinate plane, with coordinates \((0,0)\).
- 6. A number that indicates how many times a base number is used as a factor (e.g., in \(x^{3}\), 3 is the exponent).
- 7. A symbol (usually a letter like \(x\) or \(y\)) that represents an unknown or changeable number.
- 9. A mathematical sentence that compares two expressions using signs like \(<, >, \le, \ge, \ne\).
- 10. A polynomial expression with only one term, such as \(4a^{2}\).
