I came across this while looking for a good CAS calculator app. I had tried several options, such as PocketCAS, but nothing had really worked well. I remembered the old site, MyAlgebra, which could solve CAS style equations. So, partially for good times’ sake, I went back. I found that it was now called Mathway, and was much improved. This is what the new solver looks like:
The icon, though, looked suspiciously like one for an app. So, on a whim, I went to the app store and typed in “Mathway”. I then found the Mathway app.
The Mathway App
The start screen provides a quick way to access all the solvers:
The app will solve a variety of types of problems. The categories are Basic Math, Pre-Algebra, Trigonometry, Precalculus, Calculus, and Statistics, each with their own specialized keyboard. The categories reveal a student-based way of solving, by subject.
When you type something in, you will get choices on what to do. For instance, an algebra equation may allow solving, simplifying, factoring, or something else. Under the answer, there is a “view steps” button that will show work if you have View Steps purchased.
The app will solve virtually any type of problem. It will even graph if given an equation that can be graphed. Other tools include Examples, Glossary, and a Help choice to explain the app’s functions.
The app is free, and though it includes adds, you can quickly remove them by signing up for a free Mathway account, requiring only an email and password. The one way to potentially spend money is if you purchase a premium account to show steps.
All in all, it is the best CAS calculator I have seen yet. It provides an immense number of accepted problem types, and solves relatively quickly, even without internet connection. At times the responding is a smidgen slow, but not significantly. The extra tools really increase the appeal, especially for students. Best of all, it’s completely free.
