1. Is your keyboard wireless?

[left-of-center2012]

2. No

My keyboard is attached to my laptop.

[Ron Obvious]

3. Still sounds like your keyboard

Entering 12 into e.g. notepad doesn't come out 122 as well? That's utterly bizarre, almost impossible unless your calculator app or a required dll was corrupted.

10. "Entering 12 into e.g. notepad doesn't come out 122 as well?"

no

[Phoenix61]

4. Does it do that for both the number pad and

the numbers across the top of the keyboard?

11. no number pad on my keyboard

[Jacoby365]

5. Sounds like maybe a keyboard sensitivity issue.

Are you able to adjust it in your settings?

6. Not a computer expert

But that won't stop me from commenting.

I'd go with keyboard issue. Does this happen with all number keys? Just 2 and 4? The 1 seems not to be a problem. Have you entered these numbers in a document or spreadsheet? Same problem? A Google search for windows 10 calculator not working returns a bunch of repair options.

If it's software, there are a gazillion calculators available for download. Try one of these and see if the problem persists. A Google search for windows 10 calculator replacement returns an awful lot of options.

As for going online, if the issue is connectivity - no wifi, bad connection - then going online might be a pain. But if internet access is not a problem, then going online is no different than opening the calculator. Instead of clicking to open the calculator, you click to open a browser. Put your calculation in a browser address bar and hit enter. No different, really, than the app. Plus, if you're working with really large numbers, you won't encounter errors that you might on a calculator app.

12. any, all numbers

just on the calculator

7. download an HP-15, 32 or 42 facsimile app OR get a real HP with RPN.

It won't take but a moment to learn RPN, and once you do.....you'll never go back. Guaranteed. You'll wonder how you've gotten along without RPN.

8. Have used both RPN and conventional input calculators

and despite frequently hearing that once I try it....etc., I would seriously damage anyone who tried to take my HP20S.(I do use "42" on my phone configured RPN)

[yonder]

14. At least it's an HP

Isn't the 20s an algebraic entry calculator with an optional/unusual form of RPN?

[aka-chmeee]

15. 20S is a programmable algebraic

If it has an RPN option, it does not use an "Enter" key. Will have to check op manual.

[roscoeroscoe]

9. Restart!

Answer to everything

[left-of-center2012]

13. Thanks

I downloaded a different one from the Windows Play Store

[yonder]

16. Damn. RPN was staring you in the face

17. For anyone who wants the uber-geeky fix to this:

"Solution 9 – Reset Calculator app" might be the quickest one.

As all can see, he fixed his problem, and there's other solutions.
