Different Types of Calculator Apps
The best calculator apps come in all kinds. There are basic calculators, scientific ones, and specialized apps for graphing. What are the differences? Here are the basic distinctions.
As the name implies, basic calculators provide basic features for regular arithmetic operations. At the very least, these calculators will come with addition, subtraction, division, and multiplication. They should also have all the numbers, a period, and a parenthesis for added complexity. Sometimes, they can help with computations related to fractions.
However, most basic calculators won’t come with more advanced operations. Hence, they can’t help you solve complex equations for algebra, trigonometry, or even exponents. As a result, you’ll need to find a scientific calculator if you’re an engineer, accountant, or college student.
If you require more-than-basic arithmetic, we recommend using scientific calculators. These apps go beyond basic addition, multiplication, subtraction, and addition. They have special functions for exponents, square roots, inverses, pi, and trigonometry. Some can even display complex equations in multiple lines; therefore, you aren’t forced to use multiple parentheses.
Graphing calculators are much more complex than scientific calculators — but they specialize in graphing. Most of the time, these calculators prioritize the screen size to help you see graphs. You’ll only need to input the equation or function. The app will visualize it in graph form for you.
Some graphing calculators come with scientific capabilities. Not all of them do, though. So, you’ll need to assess your needs to figure out what kind of problems you need to solve most often.
The best free calculator app on Android is the stock calculator or Google Calculator. It’s great if you want something without ads. However, if you need more advanced functions, using the HiPER calculator or another app listed here is a good option.
Yes. Your Android or iOS phone’s stock calculator app and the Google Calculator have no ads.
The best calculator apps have different names and faces. Each one has a specific function that makes it different from the others. Some are free or accessible to regular users, while others are paid or exclusive to an OS. So, it is important to discern your needs to download the right app for you. You can even get multiple apps if one app can’t provide you with everything you require.
