3. Unit 2 Algebraic Expression
Definition: A mathematical phrase that can contain ordinary numbers, variables (like x or y) and operators (like add, subtract, multiply, and divide).
Model:

4. UNit 2
Coefficient
Definition: The numerical factor in a term. The number next to the variable, multiplied by the variable.
Model:

5. UNit 2
Constant
Definition: A number with no variable next to it. A fixed value.
Model:

6. Distributive Property
UNit 2
Distributive Property
Definition: The Distributive Property says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately.
Model:

7. UNit 2
Equation
Definition: When you set two expressions equal to each other. It implies that both sides of the equals sign are equivalent.
Model:

8. Equivalent Expression
UNit 2
Equivalent Expression
Definition: When two expressions have the same value.
Model: 2x = x + x

9. UNit 2 Factor Model: The factors of 42 are 6 and 7 or 2, 3, 7.
Definition: A number that can be divided from the given value evenly.
Model: The factors of 42 are
6 and 7 or 2, 3, 7.
3x = 3 * x So the factors of 3x are 3 and x.

10. UNit 2
Inequality
Definition: A statement that two values are not equal. Usually tells us which value is greater.
Model:

11. UNit 2 Linear Expression
Definition: An expression that has variables with the highest exponent being 1.
Model: 3x + 7

12. UNit 2
Maximum
Definition: The highest number or value in a given set or on a graph.
Model:

13. UNit 2
Minimum
Definition: The smallest value in a set or lowest point on a graph.
Model:

14. UNit 2 Numeric Expression
Definition: A group of known values that represent a situation.
Numeric Expression
Model:

15. Unit 2
Rational Number
Definition: A number that can be made into a fraction or ratio.
Model:

16. UNit 2
Term
Definition: A single number or variable, or numbers and variables multiplied together. Terms are separated by + or − signs.
Model:
