Hello there!
We're currently expanding our functionality and focusing on becoming the best there is at :

-

generating solutions to problems you'll find in STEM homework, tests, and quizes

-

making those solutions accessible and very easy to find (for free - students pay too much already - we would know)

-

becoming a database which has EVERY problem indexed - and with it atleast one solution - so you'll always be able to find a solution

Why?
Because we STEM Major googlers need a home.

Nothing is better than trying to solve a problem for homework and not even knowing if you did it right.

Second best is when you have the answer (only for the odd problems of course) - but can not figure out why you're getting it wrong. Is there a fundemental error? Is there a calculator mistake?

Besides this, seeing how others solve a problem can be an excellent way to learn. There are many ways to reach the same conclusion. Some of them are better than others.
