Hi,
this question is from Manchester Grammar School, I can't explain it in a simple way to my DS, except algebra.
Is there a simple way to explain it?
Many thanks in advance
Q) What is the difference between the sum of all the even numbers up to and including 2002 and the sum of all the odd numbers up to 2002?
