Since the first iPad, Apple literally forced iPad users to rely on third-party calculator apps or Spotlight Search to perform even the basic calculations, courtesy of the missing Calculator app. Fortunately, it finally paid heed to users’ plight and added the Calculator app to the iPad with iPadOS 18.

In classic Apple fashion, the Calculator app isn’t like any other app you’ll find out there; it offers a lot more. Along with the basic calculations, the app also comes with the Math Notes feature, which allows you to solve complex algebraic equations, geometric problems, and trigonometric equations in seconds.

Keep reading to learn more about the Math Notes feature in the Calculator app, now available on iPadOS 18 and iOS 18, and how to make the most of it.
