[ 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.
[ RANDM ] Generates a random real number between 0.000 and
0.999.

Other functions ( √, 3, X, x-1, x2, x3, xy , Abs,

RND )
The calculator also provides reciprocal ( [ x-1 ] ), square root ( [ √ ] ),
cubic root ( [ 2nd ] [ 3 ] ), universal root ( [ 2nd ] [ X ] ), square
( [ x 2 ] ), cubic ( [ x 3 ] ), and exponentiation ( [ x y ] ) functions. See
Example 35~39.
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 Y = A + BX
3: _+CX2 Quadratic Regression Y = A + BX + CX 2
4: ln X Logarithmic Regression Y = A + B lnX
5: e^X e Exponential Regression Y = A • e BX
6: A•B^X ab Exponential Regression Y = A • B X
7: A•X^B Power Regression Y = A • X B
8: 1/X Inverse Regression Y = A + B / X
