Mathematics

Braina can apply artificial intelligence for solving a wide range of mathematical problems. It is also a speaking calculator software. Just give voice commands to solve your math problem and Braina will speak the answer back to you.

Braina is a free software that can help students in doing their math homework. We are making it a brilliant mathematician and in near future it will be also able to solve complex mathematical problems of calculus and algebra in human readable notation.
