The main problem of "normal" calculators in the BWL is that you type functions almost flying blind and with obvious errors does not know where the problem was. One forgets quickly clamps to close or tapping under pressure, an "X" instead of a "+". This Casio allows a linear input and remembers the last entered data. The big advantage: For example. in the creation of state trees where the same function must be calculated only with different values umpteen times, you need here only the corresponding values (with the cursor) to change. This saves an incredible amount of time compared to ordinary computers. The same applies eg for interminable NPV calculations, who else really cost me nervous.
Furthermore, the computer controlled bread and butter tasks, such as determining the regression line, variances or even solving integrals (which you should verify the results again in writing). Especially great is the EQN mode that allows solving quadratic equations. In exams you should indeed do the writing, but the computer shows immediately whether you have made a mistake. In the exam priceless!
He also calculated matrices and vectors, but this is of no interest for math exams, because there may not use a calculator. To practice and to control it is, however, an indispensable aid.
However, I advise every buyer to deal calmly with all important (for oneself) features and modes, because you should (eg. In the statistics exam) can switch quickly, without first looking for one or the other menu item. If you have mastered it, you no longer are him.
Anyone looking for a computer for study's overall at baseline, should definitely buy this Casio!
He can not store formulas permanently and does not have a graphical display. In Math format he merely eg integrals graphically, but what I think is a toy, because then you constantly move the cursor to swing.
Please ask for before buying at the university, whether it has been approved !!!
