Math

2. Equation – An equation where the highest power of the variable is 2 (e.g., x² + 5x + 6 = 0).
7. – A symbol (usually a letter) that represents a number.
8. – A mathematical statement with an equal sign (e.g., 2x + 3 = 7).
14. Value – The distance of a number from zero, always positive (e.g., |–3| = 3).
15. – An expression with only one term (e.g., 5x).
17. – A single number, variable, or the product of numbers and variables.
18. – A combination of numbers, variables, and operations (e.g., 2x + 3).
20. – A mathematical statement showing that two expressions are not equal (e.g., x > 5).

1. – To multiply each term inside parentheses by the factor outside the parentheses.
3. – The value(s) of the variable(s) that satisfy the equation.
4. – A fixed number that does not change.
5. – An expression with more than one term (e.g., x² + 3x + 2).
6. – An expression with two terms (e.g., 3x + 4).
9. – To find the value of the variable that makes an equation true.
10. – A number or expression that divides another number or expression exactly.
11. – A number that multiplies a variable.
12. Terms – Terms that have the same variable and exponent (e.g., 3x and 5x).
13. Equation – An equation in which the highest power of the variable is 1 (e.g., y = 2x + 5).
16. – The number that tells you how many times to multiply a number by itself (e.g., 2³ = 2 × 2 × 2).
19. – To combine like terms or reduce an expression to its simplest form.
