To repeat a sequence of random numbers, you must store a "seed" value in
the random number generator. To store a seed value, key in an integer
greater than zero and press D
. This lets you recreate
experiments by generating the same series of random numbers. Combinations
key sequence calculates the number of combinations of n
items taken r at a time.
nCr = n!
( n − r )! × r ! Permutations
key sequence calculates the number of permutations of n items
taken r at a time.
n Pr = 8 n!
( n − r )! Chapter 1: Overview of Calculator Operations Rounding
The round function is useful when you need to perform a calculation using
the displayed form of a number rather than the unrounded value that the
calculator stores internally. The decimal format setting does not round the
calculator's internally stored value, only the displayed value.
The round key sequence
match its displayed form. lets you change the internal value to Internal value Displayed value
After rounding Before rounding For example, in the Bond worksheet, you might want to round a computed
selling price to the nearest penny (two decimal places) before continuing
with your calculation. Scientific Notation
If you compute a value that is larger or smaller than the calculator can
display in standard decimal format, the value is displayed in scientific
notation. A value in scientific notation is displayed as a base value (often
called a mantissa), followed by a blank space, followed by an exponent.
You cannot directly enter a number in scientific notation, but when the
AOS calculation method is selected, you can use the
key to enter a
number in scientific notation.
For example, for 3 10 3, type 3 < 10 3. Memory Operations
Your calculator always has 10 memories available.
The memories can hold any numeric value within the range of the
The memories are numbered 0 through 9. This lets you access each
memory using a single keystroke. Chapter 1: Overview of Calculator Oper...
