saved me 10 min per Q on my Casio calculator :)

[@sungbysam]

I typed f(x) after defining each variable but it still says variable is NOT defined. is there a problem or mistake I'm making

[@throatyv853]

Why does the calculator perform 5x slower after a year? Any fix? Can't install nover/ndless to overclock since it's not supported for the current OS version. Will replacing the battery make it return to its original speed?

[@sebber-qx5ir]

Did you find out? having the same problem

[@throatyv853]

@@sebber-qx5ir can't even get a new battery if your warranty runs out from TI smh

[@anthornt]

how could i delete the function if it's no longer useful?

[@jan_Mamu]

can’t you also use store (ctrl var)
as in x^2 store f(x)
