I discovered a website called Brainly:

It's kind of like this website. It also has answers to promblems.  

I would hope that a student's purpose in coming to this site is not to find the answers   

to problems, but rather to learn how to find those answers for themselves.

I agree withe you so, if there is another question like this you don't need to write or see if it's there. You can solve it yourself.

I like it because it has expert answers and solutions.It's cool.
