Question

Find the sum $918+737+82+263$ by suitable rearrangement

Answer 1

Finding the sum:

Using associative property for rearrangement, after rearranging, we get,

$\begin{array}{rcl}918+737+82+263& =& (918+82)+(737+263)\\ & =& 1000+1000(\mathrm{using}\mathrm{BODMAS}\mathrm{rule})\\ & =& 2000\end{array}$

Hence, the sum is $2000$.
