Um you can type like that into a calculator? Any answers please specify an actual calculator vs computer.
Sure can.
And yes I was stunned as well when I learned it, because that's not how it's taught in schools. I used to do exactly what the previous commenter did, and then one day I saw some illiterate mouthbreather type it in like that and I was like "nuh-uh, that's not how that works, gimme that thing and let me show you." And I typed it in the long and "correct" way, and whaddayaknow? Same result.
But it makes sense when you think about it, calculators were literally invented for business use (and most business people are notoriously bad at math), and one of the most common uses in business is figuring out how much something should cost after applying a discount.
Like an actual calculator or one on the computer?
It works on both. I tried the calculator apps on iOS and Windows and they both worked that way. And if you still have a regular old digital calculator, it should work on that too.
Nope just tried. 7+10% = 7.1 It converted 10% to be 0.1
Sigh. Yes on a computer/phone/browser I can see that. On a real life calculator, (which you even referenced as a "regular old digital calculator") I've not see that. That's what I've been talking about from the start JFC.
I haven't had one of these in ages but I'm pretty sure that's where I learned the trick.
Anyways, here are two videos showing it working on different models:

If it has a double zero it's probably an accounting calculator.
But in any case, in case you didn't notice when I said JFC that means I'm not interested in talking with someone that intentionally misreads what's said and posts a picture of a fucking iPhone calculator JFC. Ciao.
Okay then. Have a nice day!
Most of the ones I've used work that way.
An actual calculator or a computer?
Both? The cheap simple calculators I used decades ago would work if I typed
1then0then0then-then1then0then%. Granted, I have experience with maybe 3 calculators in my life, so I might have just gotten lucky.
