-
Match:
Rational Number
---
####
2. A number that cannot be written as a fraction
-
Definition: Numbers that cannot be expressed as a ratio of two integers, such as \( \sqrt{2} \) or \( \pi \).
-
Match:
Irrational Number
---
####
3. Counting numbers not including zero

####
4. The set of counting numbers including zero
-
Definition: The set of non-negative integers starting from 0: \( 0, 1, 2, 3, \ldots \).
-
Match:
Whole Numbers
---
####
5. Any whole number that is not a fraction or a decimal (includes negatives)

-
Match:
Integer
---
####
6. A mathematical phrase involving numbers, operation symbols, but no variable
-
Definition: An expression consisting only of numbers and operations (e.g., \( 3 + 4 \times 2 \)).
-
Match:
Numerical Expression
---
####
7. A mathematical phrase that includes one or more variables
-
Definition: An expression that contains variables along with numbers and operations (e.g., \( 3x + 4 \)).
-
Match:
Algebraic Expression
---
####
8. A symbol, usually a letter, that represents the value(s) of a quantity
-
Definition: A letter or symbol used to represent an unknown or changing value.
-
Match:
Variable
---
####
9. To replace a variable with a given value
-
Definition: The process of substituting a specific value for a variable in an expression or equation.
-
Match:
Substitute
---
####
10. To replace a value with a single numerical value
-
Definition: Simplifying an expression to its simplest numerical form.
-
Match:
Simplify
---
####
11. To find the value

13. A value that doesn’t change
-
Definition: A fixed number or constant value that does not vary.
-
Match:
Constant
---
####
14. A number that is raised to the exponent
-
Definition: The base number in an exponential expression (e.g., in \( 2^3 \), 2 is the base).
-
Match:
Base
---
####
15. How many times to use a number. How many times a number is multiplied by itself
-
Definition: The power to which a base is raised in an exponential expression (e.g., in \( 2^3 \), 3 is the exponent).
-
Match:
Exponent
---
Final Answer:
\[
\boxed{
\begin{array}{ll}
1. & \text{Rational Number} \\
2. & \text{Irrational Number} \\
