I downloaded linear algebra and the physics made easy apps and I love them both !!!!!
They are incredibly user friendly and helped me a ton, I just got a 100 on my linear algebra test using this app!
Not only are these apps a life saver but when I had a question regarding downloading the apps, the costumer service was even more impressive.
They answered me within minutes, were friendly and so helpful.
I have tried other apps before and had multiple complications with getting the apps to work and when I emailed no one was there to answer or care.
There is no other website or apps that can even come close to ti89.com and tinspireapps.com, they are truly unique.
Thank you ti89.com : you’re amazing
From your new loyal customer,
