25+897898-9/56989696996=????
Add 25 to 897898.. Now for the last part instead of dividing the whole monstrous no just divide 9/569 or till ur comfortable.. get the answer of that and put the decimal point before the no of numbers you have in the denominator for eg... 9/569 = 0.0158 There are 4 digits after the decimal one extra than the no divide.. that is n+1, so in your case put a decimal before the n+1th term from the right.. There is a more efficient method of doing it if you know calculas, if you do just let me know and Ill hook you up with it... hope this helps..
the answer you get by this or by calculas will be approx and not exact..
actually that n+1 thing is just bogus, i wrote it just so that you can understand it. I hope it doesn't confuses you...
