By far worth the money – WolframAlpha Classic Review

I'm a student who just is taking college classes instead of high school ones and this is a lifesaver. It will not only give you the answer, but a step-by-step guide to getting to that answer. Definitely a must buy for any students but calculus students especially. It will do everything from solving systems of equations to solving complex limits.
