In addition to teachers and educators receiving help in ESL postings I wonder if I could also post a message for the general benefit of educators and student community to get free help on learning math on line. The usage on http://www.onlymath.com is completely free and the web site is one hundred percent user interactive. It offers answers in real time and allows you to key in your own sums as well as create examples for you on the fly. I even helps teachers and students alike in creating the practice tests for classes KG thru 12.
