Nord Achtundachtzig

This place was a sandlot in 2008. Since then, an office building has been built here. It's called "Nord 88". I don't know why is it called like that. My theory is that it's named so because of the shape of the building. If you look at it from the top, it looks like two digits 8 on top of each other.

Nearby is the former München Olympiastadion S-Bahn station, which was built for 1972 Olympic Games. The station was closed in 1988. The tracks leading to the station were disassembled in 2003. There are a lot of rabbits in the bushes around the Nord 88 building and the derelict station.

Puzzle

The building is so complex, the locals need a map to navigate it. There is an alley going in the north-south direction. Count the maps located along the alley. This is number A. A = _______

Count floors of the building. This is number B. B = _______

Solve the following for X, Y, Z, and W:

X = A + B + 2

Y = B × 10 × A × B + (A + B + 1)

Z = (B + A) × (B − A)

W = 219 − A

To double check your calculations:

X = 20 − 2×A − B

Y = (A + B) × 100 − A × B × B + 1

Z = B × 7 − A × 5

W = 261 − A×7 − B×5
