iPadOS 18 brings the Calculator app to iPad: How to use it

After years of anticipation, Apple has finally brought the much-needed Calculator app to the iPad with iPadOS 18. At first glance, the iPad’s Calculator app looks like the enlarged version of the iPhone one. Well, it actually is, but the advantage of the iPad’s large screen makes it stand out from the competition.

However, comprehending all the new features the app offers on your own can be a bit overwhelming. So, to assist you, here’s how to use the Calculator app in iPadOS 18.

What can you do in the Calculator app on iPadOS 18?

The new iPad Calculator app packs many useful features to help you with various operations, similar to a few third-party calculator apps. Let’s explore everything you can do on the iPad Calculator app.

Basic calculation

Like any other Calculator app, the iPad’s Calculator app excels at basic calculations such as addition, subtraction, multiplication, and division. You can enter the numbers and use these operators to get instant results. While earlier, Apple only showed the calculated result, now you can view the little calculation history above the result to see what you have done.

Additionally, there is a delete button, so you can delete a number if you make a mistake while entering it. The same functionality is now available in the calculator app on iPhone running iOS 18.

Scientific calculation

Unlike on an iPhone, accessing the scientific calculator on an iPad is a bit different. You have to tap on the calculator icon located in the bottom-left corner and then select Scientific to open the scientific calculator on your iPad.

Once you enter the scientific calculator mode, you get to work with advanced functions such as sine (sin), cosine (cos), tangent (tan), logarithms (log and ln), exponentiation (e^x), square roots (√), and more, making it easier for you to solve the complex calculations and get the result instantly.

Another new feature that Apple has added to the Calculator app on both iPhone and iPad is View History. While Apple only used two to show the current session history in the Calculator app, the app induction to the iPad now offers you all the past calculation history. You can also delete the calculations from the history, which you no longer require.

Math Notes

Use the Math Notes feature in the Calculator app on iPad

The introduction of the Math Notes feature in the Calculator app was the highlight of the iPadOS 18 keynote. This feature lets you scribble your mathematical problems, equations, graphs, and more and follow it up with an equals to sign to get the answer. You can use the Apple Pencil or your finger to scribble the problems. Any change you make to the original mathematical problem is reflected in the answer in real time.

Quickly convert length, weight, currencies, and more.

The Calculator app for iPad also supports conversion for various units. You can instantly convert between currencies, units of length, weight, temperature, time, angle, area, speed, and much more.

  3. Another interesting thing is that you can make changes to the equation, and the app will update the result in real-time. For example, I could add a divide by two beneath the original equation, and the app would update the answer.
