What's new in the Calculator app in iOS 18 update

Apple usually doesn't focus on the calculator app, but with IOS 18 updateThe app has received important updates and amazing integration with the Notes app. In this guide, we review everything new in the Calculator application in the iOS 18 and iPadOS 18 update.

Among the most notable features of the Calculator app in the iOS 18 update:

Math Notes

The biggest change in the Calculator app is the addition of the “Math Notes” feature, which is an integration feature between the Calculator app and the Notes app. It allows you to write mathematical equations in the Notes application and they are automatically solved when you type the equal sign (=).

You can also perform more complex equations, defining variables and using those definitions in your calculations. For example, if you type “Dinner = $57” and “Movies = $24” in a note, you can then type “Dinner + Movies” and add the equal sign to get the sum, so Notes Math will understand what you’re referring to.

The method of defining variables and giving them a name and a value is very similar to the method of writing code.

In Math Notes, equations are solved automatically once you place an equal sign, which indicates understanding the feature that you want to solve the problem.

Technically, the Math Notes feature was originally part of the Notes app, but Apple has added the ability to use it directly from within the Calculator app. This means you can start a new math note and solve equations directly in the Calculator app without having to open the Notes app.

In other words, you can use the Math Notes feature from both apps, whether you're in the Notes app or the Calculator app, and you'll get the same functionality and features.

How to use math notes in calculator app:

◉ Open the calculator application.

◉ Click on the calculator icon at the bottom of the application.

◉ Choose “Math Notes”.

◉ Click on the new note icon at the bottom right of the screen.

◉ Start your accounts.

You can do the same thing directly in the Notes app with any new or existing note. It's the same feature, but accessed from different places.

And if you're on a math note in the Calculator app and want to return to the standard calculator interface, just tap again on the calculator icon and choose the Basic or Scientific option.

Apple says the “Math Notes” feature supports writing equations using different types of numbers and mathematical symbols. This includes:

◉ Western Arabic numerals: These are the numbers that we usually use in daily writing (0, 1, 2, 3, …). Know that these numbers were originally developed by Al-Khwarizmi and used in Andalusia, then they moved to Europe and the West since then, and were known by this name.

◉ Eastern Arabic numerals: These are the numbers that we use today in our Arab countries (0, 1, 2, 3, …) and were originally developed in India, and are also known as the Indian Arabic numbers.

◉ Devanagari numbers: These are the numbers currently used in India (०, १, २, ३, …).

◉ In addition, the feature supports common mathematical symbols such as +, -, *, /, etc.

So you can write equations with any of these types of numbers and symbols, and Math Notes will be able to understand and solve them.

Math notes on iPad

In the iPadOS 18 update, Math Notes works the same way, but there is an additional feature, which is the ability to use the Apple Pencil. Once you start a math note from the Calculator or Notes app, you can write your equations by hand and solve them the same way.

Math notes everywhere

In fact, you can type various mathematical problems in places other than the calculator and notes in the operating system, and you will get the results of “Math Notes”. For example, if you type an equation in the search, you will get a result. The same goes for other apps like Messages. We do not know whether this applies to external applications that support writing, such as social media applications? You can try it and let us know in the comments.

Unit conversion

When you use Math Notes, you can perform unit conversions. Just type what you want to convert, and you will get the result automatically. For example, if you type “10 kilograms to pounds” in the “Math Notes” interface of the calculator app, the result will be automatically generated.

Unit conversion also works in search, messaging, notes, calculator app, and more.

 Register of accounts

If you open the Calculator app and tap the three lines at the top of the interface, you can see a history of all the calculations you've entered into the app. Calculations done using the Basic or Scientific Calculator app are saved in the same app, and Math Notes are saved in the Notes app.

You can long press on any of the math problems to copy it. If you drag on it, you can delete it from the list. You can also press the “Edit” button to select multiple issues to delete, or use the “Delete All” option from this list to delete them all.

Vertical orientation of the calculator

In the past, the vertical orientation was only for using the basic calculator, but in the iOS 18 update there is an option to use the scientific calculator in this orientation, so you will not have to rotate the iPhone to the horizontal position.
