The 

[3rd][(]

 key sequence selects the Hexadecimal 

mode and shows the HEX indicator on the display 
(which is spoken out when the Special Functions 
feature mode is active). In this mode, you can 
perform arithmetic operations with hexadecimal 
numbers (integers only). 
 
When you press the key sequence above the integer 
portion of the number, the display is automatically 
converted to its hexadecimal equivalent and spoken 
out. You can enter positive hexadecimal numbers as 
large as 2540BE3FF (9 digits). Numbers beyond 
this are interpreted as negative (two’s complement) 
numbers. All keys that are not functional in this 
mode sound a warning tone. To enter the 
hexadecimal digits A through F, use the following 
keys: 

[1/x]

 [A] 

[X

2

 [B] 

[

3.11 Probability 

 

combination

 is an arrangement of objects in 

which order is not important, as in a hand of cards, 

[nCr] calculates the number of possible 
combinations of 

n

 items taken 

r

 at a time. 

 

permutation

 is an arrangement of objects in 

which the order is important, as in a race. [nPr] 
calculates the number of possible permutations of 

n

 

items taken 

r

 at a time. 

 
The

 [x!]

 

([3rd][LOG])

 key calculates the 

factorial

 of 

the displayed value which must be an integer in the 
range of 0 to 69. 
 
 
 

3.12 Physical Constants 

 
Physical constants can be entered using the 
following key sequences: 
 

[3rd] [CE/C] [SIN]

 

Speed of light 

[3rd] [CE/C] [COS]

  Gravitational acceleration 

Me
