Wolfram Alpha is google on steroids. it enables you to enter whatever information you know about anything, ask any question or ask it to solve any math problem and it simply does it. It will give you all the information it can come up with to help you solve the problem. All you have to do is enter whatever you know and it will solve it for you. As far as im concerned, there are no cons to Wolfram Alpha.
