- Textual interface – Write formulas on the left, the answer will appear instantly on the right.
- No buttons – Write your calculation as you would with a text editor.
- No need to retype – In other calculators sometimes you have to retype whole or part of your calculations, because your made a typo or a mistake in the order of the calculation.
- Use the memory of the computer – Instead of using your own memory to remember parts of the results of the calculation, Abacus keeps all previous calculations on the screen.
