Automath

Automath is a comprehensive scientific calculator that can solve every type of math operation. You can insert it either manually like on a traditional calculator or by taking a picture of the formula (with the only requirement being that the formula appear in typeface, not handwriting, so the system can recognize it).

The app can deal with simple math as well as trigonometry, algebra, fractions, or graphics. It also incorporates more than 250 preset options without having to go online, so you can use your phone or tablet as a replacement for your calculator. In fact, it's an interesting learning tool because it provides several basic tutorials from different areas of math. This, together with its graphing functions, makes Automath an important app to keep in mind for schools and other places of learning.

With Automath you can forget about all those normal calculation mistakes.
