Q1: Rounding  is often done to obtain a value that is easier to report and communicate than the original.   Rounding can also be important  to avoid misleading precise reporting of a computed number, measurement or estimate. For example,a quantity that was computed as 123456 but  is known to be accurate only to within a few hundred units is better stated as  '' 123,500 ''.


Q2: Estimating is an important part and a very handy tool for our everyday life. Get in the habit of estimating amount of money, length of time, distances and many other physical quantities.


Q3: Learn about some simple techniques that will give you a rough idea of the right answers. You can use the technique of rounding to start estimating the answer to more questions.]]> 2017-01-15 01:13:31 UTC https://padlet.com/kallytang07/5vn97ycy613u/wish/147212394
