Of course, another expressions are still there, so you don't have to reenter another expressions you don't want to remove.
If you would like to move expressions, you simply touch it and just move it to left or right.
It's very simple.
Calc touch can calculate 'Σ' ,'√'. It can operate in What You See is What You Get.
You can calculate 'Σ'. You just press 'Σ' button and specify upper number or lower number 'anytime'.

There are some click sounds and designed covers.
It's very simple and cool.
