The set of whole numbers is the set {0, 1, 2, 3, 4, 5, ...} Basically a whole number is either 0 or it is a positive number with no fraction or decimal part. ------------------------------------------------------- 2.Why is there a need for negative numbers? Negative numbers are useful for a lot of things. Examples include representing debt, showing relative position, and relative time. Ex: -2 might represent \$2 of debt. ------------------------------------------------------- 3.What numbers are not classified as integers? Fractions such as 1/2 or 6/11 are not integers because they are not whole numbers. Also, numbers such as or aren't considered integers either for the same reason. These numbers are irrational numbers. -------------------------------------------------------------------------------------------------------------- If you need more help, email me at jim_thompson5910@hotmail.com Also, please consider visiting my website: http://www.freewebs.com/jimthompson5910/home.html and making a donation.
