January 11, 2014: This
free online PreAlgebra course has been replaced with a new
version that is more complete and compatible with common-core
standards. I realize this will be an inconvenience for some of
our users, but it is an essential step that we must take.
Go to the new
PreAlgebra, version 4.1
course and be sure to reset your bookmark accordingly.
Thank you for choosing
Free-Ed.Net as a significan learning resource.
