Feature description

I wish there was a button for open/close brackets like on Google calculator.

I think it's more important than the square root or power of buttons.

Why do you want this feature?

For calculations with some bits in brackets

A separation between business and science calculator will be needed.

There then can also be brackets plus SIN COS TAN LN LOG and the both constants Pi and e.

This also enables the possibility for a third calculation mode. Computer science. Like the good old windows calculatior had.

A smartphone calculator should be able to do everyday tasks of students too.
