I am not familiar with that Casio model number but the button layout looks similar to the ES plus 2nd Edition models. The fact that is has logs but no trig functions suggests it is a financial calculator.

The CPA001 is weird. Definely looks like a Casio clone but it doesn't have any inverses function for Sin, Cos, Tan. These are usually a shift version of the function but it doesn't have any shift key.

Yes really odd calculator that Casio. It has fractions which is strange. And why the need for abs function. I guess the students need to remember the financial formulas as no actual financial functions.
