1. Prime Number whole number that has only 2 factors (1 and itself)
2. Composite Number whole number that has factors in addition to 1 and itself
3. 0&1 Neither prime nor composite
4. Even Numbers Composite (because they are all divisible by two)
5. Numbers that end in 5 Composite (because they are all divisible by 5)
6. Prime Numbers up to 2, 3, 5, 7, 11, 13, 17, 19
20
7. Interval Connected portion of the real line
8. Closed Interval Filled in circles & [ ]
9. Open Interval Open circles & ( )
10. Rational Number Number that can be written as a ratio/fraction
Ex: 8 = 8/1 3/4 7,344/123,239
*EVERY WHOLE NUMBER*
11. Irrational Number Number that can be written as a decimal but not a fraction
Ex: pi= 3.141592... square root 2= 1.414213
12. Absolute Value distance from 0 |x|
Ex: |3|=3 |-3|=3
