#90 No way to change operation after mistake in ALG mode

[onlyjob]

Description

In ALG mode if "+" pressed after "-" then subtraction will be performed instead of addition.

This is confusing and IMHO a serious usability issue as there is no way to correct such mistake (or similar) by changing next operation.

Version 2.0.1 is affected.

Example

Having typed a number (e.g. '100') then pressed '-' then '+' then '1'
the answer comes out as '99'.

Perhaps in all other calculators the result would come out as '101'
(and this seems to make more sense in case the wrong operation was selected).
