The latest update, iOS 18.3, has made a small but handy change to the Calculator app on your iPhone. They’ve brought back a feature where you can repeat calculations easily.
Here’s how it works: If you do a calculation like 5 times 5 and hit equals, you get 25. Now, if you tap the equals sign again, it will do 25 times 5. Every time you press equals after that, it will keep multiplying the result by 5.
This repeat function was available in older versions of iOS but was taken out with iOS 18. Now, with the 18.3 update, it’s back for those who missed it. It’s especially good for things like figuring out compound interest.
Also, if you use a Mac, this feature was gone in macOS 15 too, but it’s coming back with the macOS 15.3 update. So, whether you’re on an iPhone or a Mac, you’ll find this update makes math a bit easier.
