The question was: Add up all the numbers up to 100.
Der jungen Karl Friedrich didn't guess. He reasoned:
100 + 1 = 101
99 + 2 = 101
98 + 3 = 101
97 + 4 = 101
96 + 5 = 101
In this way, with the 100 numbers I can make 50 pairs, and every pair totals 101.
So all 100 numbers add up to (50 times 101) = 5,050
They say he was something like 5 years old at the time.
