To enter the same n value multiple times, enter the number, then press [2
of times you needed that value added in. For example, in the above calculation, the user needed to enter
313 four times. You would enter [313] [2
Combination (nCr)
Calculates the number of possible combinations of n items taken r at a time, given n and r.
45 nCr 3 = 14190
Permutation (nPr)
Calculates the number of possible permutations of n items taken at r time, given n and r.
45 nPr 3 = 85140
Factorials (x!)
A factorial of an integer (n) is the product of all positive integers less than or equal to n.
n!
5! = 1 x 2 x 3 x 4 x 5 = 120
Due to the limitations of the calculator, n must be a positive whole number less than or equal to 69.
Memory Functions
The Victor V30-RA has three independent memories and they are designated as M1, M2, and M3 on
the display (please note that if there is nothing in the memory, the indicators will not be shown). The
following keys are used for the memory functions:
[STO]
STO, stores the value displayed in memory. This entry will take the place of the
current value stored.
[RCL]
RCL, recalls the value in the selected memory.
nd
[2
] [SUM]
Adds the displayed value to the value already stored in memory.
nd
[2
] [EXC]
Exchanges the displayed value with the value stored in memory.
