In my university NOBODY knew how to calculate square root in paper. I still don't. :p

I would just like to point out that this isn't really proper math, it's just learning to be "human calculator", which I myself find quite boring.

Various mathematicians (professional - doing it as a job) I spoke with said that many schools don't really teach math well and make it boring. Real math is about understanding various models and concepts and relations between them, not crunching and calculating series of numbers all the time like calculator (although it's useful to understand how the things work and relate)

As programmer, you won't really need to do that, you'll need to understand the principles and how to apply or use them for your algorithms, but they'll be doing the hard work for you.

A lot of kids already find "math" boring since they were taught more to be human calculators, rather than math thinkers, I hope you won't get deterred by this as well :-)

This is easy knoww.best accurate methade is long division.....You just need to divide 49 from 32..

first you should find how many 32 to 49,,It is 1.
now you can sub 32 from 49...it's 17 and there are no 32..and you should add 0 to end of 17,it's 170.

Now you can find how many 32 to 170 and put it as a decimal...

More practice...

That works if it is 49/32 - But not if its 32/49? 32/49 is a fraction/decimal, there can be no whole number.
