[ nCr ] Calculates the number of possible combinations of n
items taken r at a time.
[ x ! ] Calculates the factorial of a specified integer n , where n
≦ 69.
[ ] Generates a random real number between 0.000 and
RANDM
0.999.

Abs Generates the absolute value of a real number
RND Generates the rounding value of a given number

Multi-statement Function

A Multi-statement is a number of individual statements grouped
together by display result commands ( ： ) for sequential execution.
When execution reaches the end of a statement followed by ( ： ),
execution stops and an intermediate result with a " Disp " icon
appears on the display. You can resume execution by pressing [ = ].
" Disp " icon disappears when the last statement is being executed.
See Example 40.

Statistical Calculations

Use STAT ( [ MODE ] 2 ( STAT ) ) mode for statistical calculations.
When you enter STAT mode, you are taken to the STAT menu with
a choice of eight calculation types as follows:
Single–variable statistics
1: 1–VAR Single-variable statistics
Paired-variable / Regression statistics
2: A+BX Linear Regression
2
3: _+CX Quadratic Regression
4: ln X Logarithmic Regression
5: e^X e Exponential Regression
6: A•B^X ab Exponential Regression
7: A•X^B Power Regression
8: 1/X Inverse Regression
