tool.
Puts an ideal combination of financial,
mathematical and statistical functions
right at your fingertips. Handles
virtually every computation needed in
modern business management from
simple arithmetic to complex time-value-of-money
problems to planning,
forecasting and decision analysis.
Procedures for more than 50
different calculations

All you do is key in your data, press.the
appropriate keys and see the answer
displayed in seconds. Automatically
computes discounted cash flow; per
centages; ratios; proportions; compound
interest; remaining balance; annuities;
depredation; mean-standard deviation;
trend-lines (linear regressions); linear
estimates; accumulated interest; rate of
return; amortization; and more.
Keystroke programmability.
The automatic answer to repetitive prob
lems. Switch to PRGM and enter your
keystrokes once. Then switch to RUN
and enter only the variables needed
each time.
Full editing capability.
You can easily review and quickly add
or change steps at will.
Branchingand conditional test
capability.
Eight built-in logic comparisons let you
program conditional branches.
8 addressable memories.
