Solves - Calculator with History

This calculator can solve long mathematical expressions and has the most required actions.

There are percent, root, exponent. Trigonometric and logarithmic functions. All actions are accessible in both portrait and landscape mode.

The input field has an active cursor, so you can make edits in any place without clearing it.

Also, there is a history of calculations. The history can be placed so that it takes a whole screen, or just about a half so you can still make calculations.
