I searched Google under the key words "compatible numbers math" to get these possible sources:
http://www.basicmathematics.com/whatarecompatiblenumbers.html
http://www.icoachmath.com/sitemap/compatiblenumber.html
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.
I hope this helps. Thanks for asking.
