Calculators

Calculators are available on your device through either Windows, Mac or a web version. Select the type you plan to use below to learn more.

Windows Built-In Calculator

A calculator application (Windows 10) already exists on your computer, accessible through the Start menu.

It defaults to a Standard calculator but can be changed to a Scientific one via the settings/options dropdown.

Visit the Microsoft website for step-by-step instructions on how to use the Calculator in Windows 10.

Mac Built-In Calculator

A calculator is a native app in iOS/macOS.

If you own a trackpad, access it by using five fingers on the edges of the trackpad and dragging them together to a point to get the list of apps to select the calculator.

If you do not own a trackpad, open the Launchpad or Spotlight to search for the calculator app.

The calculator defaults to a Standard calculator but can be changed to a Scientific one via the View menu.

Visit the Apple Calculator User Guide for more information.

Online Calculators

Numerous online calculators are sufficient for ERAU math courses. Online calculators are browser-based and require access to the internet.

Our top recommendation is Desmos Scientific.
