  5. Jan April 12, 2020

    I have several of the basic calculators for daily use.
    But there is one important problem with them: the annoying Auto-power off function! It too often destroys your work.
    You calculate a number, then you work with the number (I’m talking about the professional business work), which can take some time and when you need the number again – it is gone. The calculator was powered off autimatically.
