    when i type =1-.78-.22, I get 0 but when i enter =(1-.78-.22), i get error result -2.77556E-17. If i ask the expert, it was told that this is due to some hidden errors while deducting. Will this error would not modify the result of calculation if it is in the centre of a multiple formula.
    This error, i think, was not found in the ms office 2003. Was there any correction by the microsoft in this regard. pl

    Ok.cmos you are correct, but normally when you place =sign, the excel takes anything as formula, and formula is obviously with numbers only. Why you have to format it to get this. So , should it mean that you have to format all the cells before entering formula
