xThink Calc: Online Calculator for your Drawing Pad

Online calculator with a twist. xThink calculator lets you write and solve problems using your mouse instead of a keyboard. You’re provided with a dashboard where you can only use the mouse cursor (or external drawing pad) to sketch a problem, for example if you scribble 34×57 and click “Solve”, xThink will calculate it and show you the solution.

Pretty handy website for those who got a drawing pad. As for everyone else there are eCalc, InstaCalc and Calc5.

xthink Features:

• Write and solve your scientific calculations using your mouse.
• Generate solutions in DEG or RAD units.
• Set preferred decimal precision.
• Add personal notes.
