Question
Determine the sum by suitable rearrangements:
$2359 + 1000 + 2641 + 9999$
$2359 + 1000 + 2641 + 9999$
✓
Answer
$2359 + 10001 + 2641 + 9999$
Therefore, $59 + 41 = 100$
And, $99 + 01 = 100$
Therefore, $(2359 + 2641) + (10001 + 9999)$
$= (5000) + (20000)$
$= 25000$
Therefore, $59 + 41 = 100$
And, $99 + 01 = 100$
Therefore, $(2359 + 2641) + (10001 + 9999)$
$= (5000) + (20000)$
$= 25000$
