Foundations of Algebra 2

1. Parts of an expression or series separated by + or – signs, or the parts of a sequence separated by commas.
5. A quantity that can change or that may take on different values.
7. A transformation in which a plane figure turns around a fixed center point.
8. The most common number.
9. Any and all value(s) of the variable(s) that satisfies an equation, inequality, system of equations, or system of inequalities.
11. The ratio of each term of a geometric progression to the term preceding it.
12. The average.
16. The set of input values of a relation.
18. A mathematical sentence built from expressions using one or more of the symbols <, >, ≤, or ≥.
20. An equation that relates two or more quantities, usually represented by variables.
21. The number that corresponds to a point on a number line.
24. A polynomial with one term.
25. A transformation in which a geometric figure is reflected across a line, creating a mirror image.
28. The number or variable that represents the number of times the base of a power is used as a factor.

2. Any mathematical calculation or formula combining numbers and/or variables using sums, differences, products, quotients, exponents, roots, logarithms, parentheses, brackets, functions, or other mathematical operations.
3. The set of y-values of a function or relation.
4. A set of ordered pairs.
6. To figure out or compute.
10. The number multiplied times a product of variables or powers of variables in a term.
13. A transformation in which a figure grows larger.
14. The middle number.
15. A relation for which each input has exactly one output.
17. To multiply out the parts of an expression.
19. that have the same variable parts.
22. To use the rules of arithmetic and algebra to rewrite an expression as simply as possible.
23. The sum of the terms of a sequence.
26. A statement that two expressions are equal.
27. The mathematics of working with variables.
