Using your device’s camera, you can scan almost any mathematical equation and Photomath will show you the solution. It’s available free on both iOS and Windows products, but not quite yet for Android. Photomath is an awesome little app that really uses the power of current technology. You can get the answer in either degrees or radians. While our other two calculators on this list so far have been a bit more complicated, this simple online trig calculator will help you find the sine, cos, tan, cot, sex, and csc with a simple click of a button. If you want to upgrade to the pro version, you can see more detailed explanations on solutions. You can even ask Wolfram Alpha questions on other topics like biology, physics, and even history. You can type in almost any mathematical function or question and Wolfram Alpha will give you details on the formula, a solution, and a simple step-by-step explanation on how to get the answer. Wolfram Alpha can be accessed on any computer and it has a mobile app as well. If you have an iOS device, a comparable option is the Free Graphing Calculator app. You’ll also have access to statistical functions, algebraic equation solving, and more with this free app. ![]() You’ll be able to calculate complex scientific equations (square roots, logs, trig functions, inverse functions, etc) along with advanced graphing options (graph multiple functions at once, parametric functions, polar graphs, etc). It has the same functions as a physical graphing calculator with arguably better-looking graphs and visuals. It provides one of the best designs and visuals of free graphing calculator apps. This particular app is only for Android users. This really isn’t necessary with apps like Graphing Calculator by Mathlab Apps. Graphing Calculator by MathLab Appsīuying a new graphing calculator like a TI-84 can cost well over 100 dollars. Let’s go over 9 of the best free calculators you can use for a variety of applications in mathematics. If you don’t have the money to get these kinds of calculators, there are free math calculator options for you.Īnd even if you just need help factoring or solving a simple quadratic equation, there are free calculator options for you too. Scientific and graphing calculators can cost hundreds of dollars. But as your problems get more complex, the calculators you need to solve them get more expensive. You can just install it using your distributions regular method.Despite what your first-grade teacher might have told you, calculators are an essential tool for solving mathematical equations. And the more advanced features are there the few times you do need them.Īll the Linux distributions have SpeedCrunch in their repositories. It really isn't all the scientist-specific features that make SpeedCrunch such a nice calculator, it's simply very efficient to use for all purposes. It probably is a great calculator for those use-cases. SpeedCrunch advertises itself as a calculator for rocket scientists. How these are placed and configured is remembered when you close it so you get an identical layout the next time you open it. These items can be detached into their own separate utility windows. You are not limited to Pi and the Golden Ratio and a few more like you are in KDE's KCalc.įormulas, functions and constants are placed in an area on the right of the calculation terminal window. There's a vast amount of formulas and more than 150 built-in constants. It can be configured to only show the terminal window and it can be configured to show a keypad, constants, functions, variables and a formula book. ![]() It displays a "Current results" above the numbers you enter as you type and the final result's shown in the "terminal" together with the numbers or equation when you press the Enter key. SpeedCrunch has a terminal-like window where you can enter numbers right away. It's a great choice if you are looking for something to assign to that Calc(ulator) key found on many modern keyboards. The homepage describes it as a "high-precision scientific calculator" and while that's true it is also the by far best general-purpose calculator available on Linux platforms. SpeedCrunch is a very efficient and easy to use free calculator program for Linux, Windows and macOS.
