I am still struggling with the after effects of Linux reinstallation on my system. Two major problems: 1) Firefox and openoffice is still not in English. Its giving me hard time. 2) The functions in openoffice  version of excel is not working. I am yet to sort that out. In the mean time, I desperately needed it to do simple task. subtracting values of one column from one in another column and write the difference in next column.
