Easy to see, easy to correct!
Takes the frustrations
out of calculations!
The Trackback Difference
• TrackBack calculators are business calculators that perform
profit analysis with just 3 keys.
• The 2-line alphanumerical display clearly labels calculations
and shows calculation history.
• The functionality to review, verify, and correct calculations
and analysis is one of a kind.
• TrackBack calculators provide an undeniable upgrade in
performance from the popular TI BA-20 Profit Manager.
The Trackback Difference
1. Review and correct
Have you ever asked yourself,
"Did I enter all values correctly?”,
when hitting the Equal key after entering
a long list of numbers?
With the Trackback, even after
completing a calculation, you can easily
go back and correct entered values.

2. No more guesswork
Never have to repeat the tedious work of
crunching numbers to verify your results.
With Trackback, you can review and
update entries just like you can in Excel.
The Trackback Difference
3. What you see is what you get
Unlike traditional calculators, the
Trackback will automatically calculate
based on order of operation rules. For
example, to calculate 7+7÷7+7x7-7,
just enter the equation as written, and
you’ll get the correct answer.
The Trackback also displays text,
allowing you to know the specific
function being used, such as "Tax",
"Profit", "Cost" and "Sell”.

4. 1000-entry trackback
The Trackback can store up to
25 calculations with an average of
40 characters.
Current entries can be reviewed with the
left/right scroll keys and previous
calculations can be recalled with the
up/down scroll keys.

5. 2-line alphanumerical display
The Trackback’s large
2-line alphanumeric display
combines the editing
capability of spreadsheets
with the simplicity of
calculators.
