### Student Testimonials:

"I could not imagine how much time and money it would have taken if I went school for this." — Ahmed M.

“Best teacher ever.” — Carreola A.

"I am a homeschooling parents and you are making my life easy." — Jimmy G.

“This is a great visual presentation. Many years ago I tried to explain how to add and subtract integers to an 8th grader and failed miserably. Had I explained it the way this presentation does, the child would probably have understood how to do this.” — Jeanette A.

“Your basic math instruction is excellent. I love your teaching style.” — Earl W.
