calculator doesnt work correctly anymore

My calculator doesn't work right anymore which I suspect might be due to a recent update 17.7.

Ive used the calculator for 10 years or more compute parallel resistors ohms. It's a simple operation, but now it doesn't give me the answer like it did before. I deleted the calculator and reinstalled it, but same goofy results.

So I deleted the app and downloaded another calculator app. Performed calculation and same screwy results.

Completely befuddled, I went online and used a calculator online and it worked exactly like it was supposed to.

So, either my iPad is doing has some buggy calculations functionality or I am now in some other reality/dimension. 😎

Here is a screen shot of the calculation. I must admit the answer is correct as far as the reciprocal but you are supposed to "flip" this number using the 1/x function to get the actual resistance value. And it doesn't do that anymore like the online calculators do. Oh and BTW, my iPhone calculator (same one) works correctly. Go figure

Thanks in advance ... I hope someone has a clue as to what's going on.
