Expressions

3. Terms that have the same variable raised to the same power (e.g., 2x and 5x
5. The process of simplifying an expression by adding or subtracting like terms.
10. To combine like terms and perform operations to make an expression more concise
11. The numerical factor in a term with a variable
12. An operation that reverses another (e.g., multiplication and division, addition and subtraction)
14. The largest number or expression that divides two or more terms exactly.
15. A letter or symbol that represents an unknown value
16. The process of writing an expression as a product of its factors

18. a mathematical statement with an 'equal to' symbol between two expressions that have equal values

1. To apply the distributive property to rewrite a factored expression as a sum or difference
2. property: when you multiply a number by a sum (like two numbers added together inside parentheses), you can multiply the number by each individual number in the sum, then add the results together
4. the relationship between factoring and expanding/distributing
6. a statement involving at least two different numbers (known or unknown) and at least one operation (no equal sign)
7. property: you can change the order of numbers when adding or multiplying them, and the answer will still be the same
8. A number or expression that divides another number or expression evenly.
9. A number on its own, without a variable
13. property: when adding or multiplying three or more numbers, the result stays the same no matter how you group the numbers together using parentheses
