1. whole number: set of numbers that contains no fractions or decimals (0,1,2,3,4,189,
293)
2. Intergers: whole numbers and their opposites (negatives)
(-1, -2, -3, -4, -5, 0, 1, 2, 3, 4, 5
3. prime number: number that is only evenly divisible by 1 & itself
- no remainder or decimal
4. composite number: positive integer (whole number) formed by multiplying 2 smaller
integers together
- all divisible by 2
- can be evenly divided by numbers other than 1 or itself
5. decimals: what follows decimal is a value less than 1 & added to the integer number
preceding the decimal
- division between the whole portion & the fraction (or decimal) portion of a number
- EX: 3.15 3=whole; .15=decimal/fraction
6. real numbers: rational and irrational numbers
7. rational numbers: any number that can be expressed as a fraction, w/ a non-zero
denominator
- all integers are considered rational numbers
- every rational number has a decimal that terminates/repeats
8. irrational numbers: numbers that cannot be expressed as a finite decimal -Pi is
finite bc its decimal portion is unending

, 9. communitive property: a+b=b+a
10. Associative Property: grouping of numbers doesn't matter in an addition problem
11. decimal chart: place value of decimals
12 In dividing by 10, you move the decimal 1 position to the: left, making a smaller #
than before
13. In multiplying by 10, move the decimal 1 position to the: right, making a
larger # than before
14. kilo: 1000 units

19. centi: 0.01 units
20. milli: 0.001 units
21. addition & subtraction of decimals: line up decimal
22. multiplication of decimal: pretend decimals are not there, then count how many
decimals are in original problem; use total to place decimal in same number of
spaces over
23. proper fraction: the numerator is less than the denominator
24. improper fraction: the numerator is larger than the denominator
