If math is not your strong subject, Wolfram Alpha may just have the apps for you with its new dedicated calculus and algebra Course Assistants.
These apps give you the ability to solve complex mathematical equations, including graphing and expanding polynomials.
Each function features unique keyboard symbols depending on what you’re trying to do, whether it’s solve equations, graph them on an x/y plane, integrate functions, or even work with series. The apps even give you the relevant intermediate steps taken to reach the given result.
The newly-released Android versions of the Calculus Course Assistant and Algebra Course Assistant will run you $3.99 and $1.99, respectively, and you can also nab their iOS counterparts (which have been out for a while now).
