xThink.net - Online scientific calculator

Are you tired of not having enough space on your calculator screen, or maybe it is just too small to see? Well, now your problems can be solved. xThink delivers a scientific calculator to you through the internet, in a web browser interface. The user can use a digital pen, or mouse to write the equation in the work space. Scientific calculations and annotations can be made. Solutions and calculations still in the problem solving stage can be saved and returned to at a latter time. The calculator can also learn to identify your writing, if it is having difficulties identifying your marks.

“With xThink® Online Calculator you start writing and solving problems immediately (no keyboard needed!).”

Calculators are small and the screens can be difficult to see. With the web browser interface both of those problems are eliminated. Also, long calculations can become unorganized and difficult to retrace, xThink can also help with that. It is like problem solving on paper, but it solves it for you, all you have to do is write the equation. It could become a very useful tool for students, professors and researchers.

Can equations and solutions be saved for longer than one session? If the user doesn´t want to use the mouse to digital pen, can they use the keyboard?
