Therefore answer gap of estimation and approximation is wide. E.g: The actual answer is 13 X 16 = 208 . In estimation, it becomes 10 X 20= 200 where as Approximation is 13 X 16~210. Approximation is closer to the answer than estimation. Estimation is easier to work out but answer may be off while approximation is harder to work with but the answer is more accurate.Darren Teohttps://www.blogger.com/profile/14412703404809341783noreply@blogger.comtag:blogger.com,1999:blog-7195787896650777325.post-84968947185862461452011-03-01T13:33:37.630+08:002011-03-01T13:33:37.630+08:00Approximation and Estimation
