    Find the sum by suitable rearrangement:
    (a) 837 + 208 + 363
    (b) 1962 + 453 + 1538 + 647

    Answer:

    (a) \[~837+208+363=(837+363)+208\]
      \[=1200+208\]
      \[=1408\]                                                                                                                   
    (b) \[1962+453+1538+647\]
    \[=(1962+1538)\text{+(453+647)}\]
    \[=3500+1100\]
    \[=4600\].
