Thank you very much, Dwarf, for taking the time to help me, but so far when I look there, all I can find is a calculator help file. Maybe I can get my son on the job here soon. He will probably see what I am missing seeing.
The Windows 7 calculator is a beautiful thing, but I only use scientific notation and such once every 10-to-the-third years or so. To me the Windows 98 calculator makes a simpler visual statement for adding columns of figures and such.
