I think everyone has at least one or two calculators in your office or home but probably it never gets any attention of yours because the calculator has not changed since the liquid crystal display had replaced fluorescent tube and LED displays in 1971.
Collaborating with Datexx, The TrackBack 2-Line Calculators are born!
It looks like ordinary desktop calculator but there are big differences in the functions:
1. 2-Line Alphanumerical Display - It displays what you have just entered and function you have just selected.
2. Cursor Keys - Back, Forward, Previous, Next keys allows you to verify and correct entries and calculations.
3. Textbook Style Expression Display - You can enter the mixed calculation such as 7X7X7+7÷7 without rearranging the order.
4. Profit Margin Calculation - This function allows you to figure out Cost, Sell price and Profit Margin with a text confirmation.
5. Programmable Tax Calculation - This function allows you to program tax rate and calculate the Tax+, Tax–, and Tax at your fingertips.
