I can't understand logic of [C] key (not ) on simply calculators like fx-260

[+] [*] [^] [C] [*] [=] 19

and

[+] [*] [^] [C] [+] [=] 12

So, pressing [C] key, calculator clear not only last number, but all calculations after [+]?

[*] [(] [+] [*] [^] [C] [+] [=] 36  ???

It clears the contents of the screen, but not memory

I currently don't have my fx-260 with me, but if you do 2+2 then *2 then press C then type in 5 equal then it should equal to 20.

Your example 2+2 then *2 does not include a change operation after clicking [C]

What shoud be if press 2+2 then *2, then [C] + 2 = ?

I don't have my calculator with me, it says C clears the display input value. so it just deltes what you just inputed but no your previose stuff

If you do 2+2=4*5 [C] 2 = 8
