Is my vision that bad? No, it's just a bug in Apple's Calculator

On mobile devices, Apple’s Calculator app has always been one of the most frustrating apps I’ve ever used, and I’m surprised it’s a stock app by the company itself. If you press buttons quickly, like you would a normal calculator, many of the key presses simply don’t register at all. I’m not sure if they’re prioritizing some pretty little visual animation over actual functionality, but it’s incredibly surprising from a company that focuses on user interaction, supposedly.

I switched to an iPhone a few years ago and I really miss the Android calculator app. It showed the entire expression typed so far and its current value! In desperation, I have resorted to SSHing to my desktop and using `python` as a calculator.

You can use Siri Search on iOS as a calculator, which works the same way as Finder on a Mac — this keeps track of the entire expression when you’re doing it

With the added benefit of having to press not just one, but two buttons in order to add a "+" sign. First press "123", then press "#+=" and now you can add your complex mathematical characters :)
