iOS 11: New iPhone calculator adds animations that make adding up difficult
Apple isn't re-writing the rules of maths. But it does look that way

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Sometimes, 1 + 2 + 3 doesn't equal 6.
That's according to the iPhone's new calculator, which behaves bizarrely and gives out results previously thought impossible using normal maths.
The strange animations that have been added to the iPhone calculator stop you actually using it to add up.
If you do the above calculation, for instance, you'll more often than not end up with a result like 24. That's because the animations that show when you press a button last so long – and you can't press another button until the animation.
Practically, that means that the phone will probably miss out the second add button, when you press it. Because the iPhone calculator doesn't register that press, it thinks that you've written 1 + 23, and gives you the correct result for that answer.
So there's nothing wrong with the iPhone's maths. But it's likely to make you think there's something wrong with yours: the slow, strange results could easily lead to getting things wrong, which might be worrying if you're using the numbers for something important.
To make sure that the iPhone's numbers are right, the best thing is to wait until the animation has faded and press the button again, while at the same time making sure the number has appeared in the read-out at the top. (There are also other calculator apps, like PCalc, available in the App Store.)
A number of Apple commentators have pointed out the problem, and a bug has been filed in Apple's internal bug reporting system.
The change appears to have been introduced with iOS 11, the new operating system that came out with the iPhone 8 in September. That brings with it a range of other – less perplexing – hidden features, which can be found here.
