Some of my tests were common physics and geometry equations shot from webpages. Although entering equations simply by photographing them is a great idea, in practice the app didn't do well in recognizing some of the characters.

I had the most success with the keyboard, though it took some trial and error to enter certain items like exponents properly. There are two ways to enter an equation in Mathways: either by using the keyboard or by photographing the equation with your iPad's camera. What differentiates them is the other third of the keyboard, whether it be the geometric shapes in Basic Math, the Trigonometry calculator's 24 functions, or Calculus's logs, summations, integrals, and limits, to name a few. If you press Sin and enter x, a list of operations appears under the question 'How should I answer?' Pressing the first item, Graph, calls up a graph of a sine curve, for example.Īll 10 of the calculators share the left-most 2/3 of the keyboard, which includes commonly used symbols such as the integers 0 through 9, the variables x, y, and z, open and close parentheses and brackets, signs for the four basic operations (addition, subtraction, multiplication, and division), an equals sign, exponents and roots. Similarly, in the Trigonometry calculator, tapping the keyboard's Sin/Cos brings to the foreground a keypad with 24 buttons-Sin, Cos, Tan, Sec, Csc, and Cot Arcsin, Arccos, and so on. If you input a value, say 1.3, and press Enter, a menu with the title 'How should I answer?' appears, offering 10 choices, among them Find the Area, Find the Circumference, Graph, Evaluate the Function, and Convert to Radical Form. For example, pressing the calculator's key marked with a circle calls up a circle with a dotted line denoting its radius ( r), followed by ' r = ?' with the question mark shaded in gray, inviting you to enter a value for r. To figure out how the functions work, you have to explore them, as the app doesn't have a ready Help function (although the Mathway website offers a lot of information). For example, the Basic Math calculator includes keys marked with various geometrical shapes: square, circle, triangle, cube, cone, sphere, and cylinder, among others. Other subjects are also covered, but would appear under one of the headings above. A Cornucopia of CalculatorsĪt the top left corner of the screen is a list icon (three stacked lines) that when pressed reveals a pull-down menu listing the app's 10 subject areas: Basic Math, Pre-Algebra, Algebra, Trigonometry, Precalculus, Calculus, Statistics, Finite Math, Linear Algebra, Chemistry. I first looked at the free functions, and then tested the paid functions by paying for a monthly subscription. I tested it with an iPad Air 2 running iOS 10.3.

Mathway is compatible with the iPhone, iPad, and iPod touch there's also an Android version. If you tire of the paid version, or it doesn't fit your needs, it is easy enough to cancel your subscription from your iPad's Settings menu. You are charged through your Apple account, rather than directly from Mathway. You then select between the $19.99 monthly and $79.99 yearly subscription, and when prompted, enter your Apple ID.

To upgrade the app, you tap the Upgrade button that appears in a pull-down menu when you tap the gear icon at the screen's upper right. (Opens in a new window) Read Our WolframAlpha (for iPad) Review

Furthermore, the paid version can act as a valuable 'virtual tutor' for students, not just giving them the answers but also showing how the app arrived as them. Depending on the length of time you enable step-checking, it can run into some money, but your subscription can easily be canceled. It also lets you save your problem history, and access the step-by-step solutions from anywhere. Paying removes all third-party advertising (not that there is much in the free version). Upgrading to the paid version costs either a $19.99 monthly subscription or $79.99 per year. If you want to see the steps that go into solving the problems, you have to pay. The basic Mathway app, which lets you solve problems using its virtual calculators, is free. It's a valuable resource for both students and scientists, making it an Editors' Choice educational app. Furthermore, the app can help you frame the problem to be sure it delivers what you need. Whether you're working with basic math, algebra, calculus, trigonometry, chemistry, or statistics, Mathway can launch a calculator (in a virtual keyboard) with the symbols and tools for the type of problem you need to solve. The Mathway - Math Problem Solver iPad app is 10 calculators rolled into one.
