“Differential Equations Made Easy (TI-89) breaks down each step which really helps you understand the problem.

The Differential Equations Made Easy program saved me from hours of wasted studying.

The program breaks down each step witch really helps you understand the problem.

This also guarantees your answers are correct and gives you that peace of mind in Homework and beyond.

The program itself is intuitive and easy to use.

I opened it and immediately knew just how to do operations without referring to their detailed menu.

I can also speak volumes to the quality of the customer service.

They respond instantly and answered every question with professionalism.

I have come back time and time again and recently purchased the Physics Made Easy.

There is so much power packed into these programs.

Thank you TI89.com!
