En tal glad geocacher boede på en vej hvor husene var nummereret fortløbende fra 1 og opefter. Der var mindre end 10 huse på denne vej. Det der gjorde ham særlig glad var at summen af husnumrene før hans og summen af husnumrene efter hans var lig hinanden.
Han ville dog gerne have nogle flere naboer og ønsker at flytte til en ny vej med mere end 10 huse og mindre end 100
A = Nummeret på hans nuværende hus
B = Antal huse på hans nuværende vej
CD = Hans kommende husnummer
FG = Antal huse på hans kommende vej
N55 0 (B - 1) . (CD * 9) - 8
E08 5 (A - 2) . (FG * 6) + 3
A geocacher that was odsessed with numbers lived on a road where the houses were numbered consecutively from 1 upwards. There were less than 10 houses on this road. What made him particularly happy was that the sum of the house numbers before him and the sum of the house numbers after him were equal.
However, he wanted some more neighbors and wanted to move to a new road with more than 10 houses and less than 100
A = The number of his current house
B = Number of houses on his current road
CD = His future house number
FG = Number of houses on his way
