Editing Comments on SquaringNumbers

### 3 Comments. ### This is fine upto 125^2, now how about methods for mentally squaring the real tough ones, eg. from 201^2 to 998^2 ? What is the method of holding the intermediate numbers in ones head while doing the mental work to get the final answer ? -- ahmedsyed41 2010-04-18 12:13 UTC
