Even advanced mathematical calculations are simple to perform and functions that take advantage of previous unavailable display capabilities are now possible.

Spreadsheet calculations


The spreadsheet function can be used for studying statistics which has become important in mathematics classes.

Example: Student’s height data comparison chart

Statistical calculation such as the mean of the data is executed


In addition, the spreadsheet function makes it possible to enter recursive formulas.

Sequence: a1=2 and an+1 -2an-3 (n=1, 2, 3 …)

a1-2, a2=1, a3=-1, a4=-5, a5=-13

Riemann Integral

Calculation using advanced Riemann functions is also possible.

The spreadsheet function makes it easy to use real-world data even in the classroom, enabling students to effectively study statistical processing.
