Notes can be added next to any of the expressions to remind yourself of why you added something to the graph or to help you study. Here's something I think is awesome for learning: If you tap an area of the graph, it will highlight the expression to show you exactly which one is responsible for that specific area of the graph. It also supports function transformations via slider buttons, so instead of adjusting the expressions manually, you can just slide the bar left or right to quickly decrease or increase the value. One of the major differences in this graphing calculator app versus some of the others you might find is that it doesn't limit the number of expressions you can graph at once. The small keyboard can sometimes be hard to useĭesmos is the absolute best free graphing calculator for Android, iPad, and iPhone, and because it works online, too, you can save your graphs and edit them anywhere. Premium is as low as $3.33 /month if you pay $39.99 for the whole year. ![]() Mathway works on the web and is free for iPad, iPhone, and Android. In fact, if you begin a graphing problem but don't plot it, and then move to some other category, you'll lose that progress. The only exception is that there isn't a history of previous graphing problems. This is smart, and I'm glad it's included. The app keeps a history of each section in the respective categories, so you can always return to Trigonometry, for example, to see those problems and answers even after you open a different area of the app. It gets confusing if multiple areas are mixed into one big calculator, like how some calculator apps work. ![]() The app is chock-full of functions for several areas of math, so it's great that each category has its own section, like one for basic math and another for linear algebra. It's free to see answers, define terms, and plot points on a graph, but if you want step-by-step work and detailed explanations, you'll have to subscribe to the Premium version. It covers basic math, pre-algebra, algebra, trigonometry, precalculus, calculus, statistics, finite math, linear algebra, chemistry, and graphing. Mathway might be the only calculator you need.

However, something to be cautious about is the matched solutions feature, which can cause some confusion. Solutions can be shared with others so all they have to do is open a link to the Photomath website to see the problem and the answer.You can also favorite them to quickly find them again. A history of every equation you run through this app is stored for you to return to at any time.From there, you can see every step necessary to solve it. After taking a picture of the problem, the app lets you edit it in case it didn't read it correctly.Here are some noteworthy features I want to mention: I've used it a handful of times with my son and can confidently say it's a godsend if you're struggling with a math problem. Unlike a standard calculator app that makes you manually type the whole math problem, this one does it automatically-just take a picture of the problem to get the answer.Įven better, Photomath shows you exactly how it got the answer, showing every single step necessary to solve the problem.
