prime number - ANSWERnumber that is only evenly divisible by 1 & itself
- no remainder or decimal
composite number - ANSWERpositive integer (whole number) formed by multiplying
2 smaller integers together

- can be evenly divided by numbers other than 1 or itself
decimals - ANSWERwhat 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
