Is that true though? We’ll never know. One of the great mysteries

I thought it was the other way around and CE was clear entry, C was clear.

That’s how it works on the adding machine I use at work. That might not be universal, but if I input something wrong I press C and retype it, meanwhile if I need to reset it all I press CE.

Clear and Clear Entry.

The better option is to use an RPN calculator as Hewlett-Packard used to make. Then the back arrow button just eliminates one digit at a time.

So it’s not just me who’s wrong! Good good. See you in math hell
