Temporary memories (A-H, X-Z)
Press g and the variable key to store a value in memory.
Press f and the variable key to recall a value from the
memory.
To place a variable in an equation, press
i
and the variable key.
Independent memory (M)
In addition to all the other features of temporary memories, a
value can be added to or subtracted from an existing memory
value.
Press
s g M
to clear the independent memory (M).
Last answer memory (ANS)
• The calculation result obtained by pressing = or any other
calculation ending instruction (including storing and recalling
operations) is automatically stored in the last answer memory.
• Listed fi nancial variables are automatically stored in the last
answer memory by displaying the variable and the value.
TVM variables
TVM variables can be recalled using
f
in the same way as
temporary memories. It is not necessary to press g to store
a value.
Listed fi nancial variables
Financial variables are specifi c to the type of calculation they
are used in. For example, the variable N is available to the TVM
solver but not to discounted cash fl ow analysis calculations. If
you want to carry a value from a variable over into a different
type of calculation, use one of the following methods:
• Last answer memory (ANS): Within the original calculation, dis-
play the variable and value that you wish to carry over. The value
is automatically entered into last answer memory. Press
s
to
exit the calculation (the listed fi nancial variables will disappear
from the screen), and press
i
/ to bring up the value
from the previous calculation. M-D-Y (D-M-Y) 1 and M-D-Y (D-
M-Y) 2 are not stored in last answer memory.
• Variables common to both calculations: If the value that you
wish to carry over is held in a variable that exists in both types
