Reasons for recommendation: This is an excellent tool that everyone should know about. It allows you to solve almost any math question! It even allows you to use unknowns and will still get the proper answer for you! I feel that this is useful as if you are stuck on a math question, you can enter it here to get the answer and work backwards. It is a very easy way to learn.
