Classifying Numbers

4. Refers to the process of placing points on a coordinate plane using their x and y coordinates. It usually involves drawing on a graph or map to represent data visually, demonstrating relationships between variables.
6. A rough calculation of the value, number, quantity, or extent of something
7. This is the bottom number in a fraction. It shows how many equal parts the item is divided into.
9. A positive integer with no divisors other than itself and 1.
11. Numbers that equal the product of a real # and the imaginary unit "i", where I ^2 = -1. The number is 0 is both real and imaginary
12. (per 100) From the Latin per centum "by a hundred" this is a number or ratio expressed as a fraction of 100.
14. Numbers that can be expressed as a ratio of an integer
15. The Inverse of a value or a number. If n is a real number its reciprocal is 1/n. All numbers have a reciprocal except for 0.
17. # Any number that is the root of a non-zero polynomial with rational coefficients.
18. # A positive integer that can be factored into a product of smaller positive integers. Every integer greater than one is either prime or composite

1. The relation between two expressions that are not equal, employing a sign such as = "not equal to," > "greater than" or < "less than".
2. Includes natural #s and zero
3. The process of determining the number of elements or objects in a set or group.
5. #s Also known as mixed fractions which consist of a whole number and a proper fraction
8. Includes whole #s and their negative counterpart
10. Real Numbers that are not rational
13. #s used to count object (1, 2, 3, …)
16. This means arranging numbers in a sequence either in increasing or decreasing order.
