Så lidt, jeg har jo 4999 og 5001, hvilket giver 10.000 ;-)
Hmm, det gør 4998 + 5002 også.. CRAP!

Din aha-oplevelse minder mig om en gammel historie om fysikeren Gauss:
en.wikipedia.org/wiki/Carl_Friedrich_Gauss#Early_years skrev:Another famous story, and one that has evolved in the telling, has it that in primary school his teacher, J.G. Büttner, tried to occupy pupils by making them add up the integers from 1 to 100. The young Gauss produced the correct answer within seconds by a flash of mathematical insight, to the astonishment of his teacher and his assistant Martin Bartels. Gauss had realized that pairwise addition of terms from opposite ends of the list yielded identical intermediate sums: 1 + 100 = 101, 2 + 99 = 101, 3 + 98 = 101, and so on, for a total sum of 50 × 101 = 5050 (see arithmetic series and summation).[3] J. Rotman states in his book A first course in Abstract Algebra that he believes this incident never happened.
