Below is an instruction that describes a task. Write a response that appropriately completes the request in German. Please answer in German.

### Instruction:
 John has to restring 3 basses with 4 strings each, twice as many guitars which have 6 strings each, and 3 fewer 8 string guitars than the normal guitars. How many strings does he need?


### Response:
 Die Bässe benötigen 3*4=<<3*4=12>>12 Saiten.
Er bespannt 2*3=<<2*3=6>>6 normale Gitarren.
Das erfordert 6*6=<<6*6=36>>36 Saiten.
Er bespannt 6-3=3 Gitarren mit 8 Saiten.
Das bedeutet, er benötigt 3*8=<<3*8=24>>24 Saiten.
Insgesamt benötigt er also 12+24+36=<<12+24+36=72>>72 Saiten.
