D\i=5, r=27
d+i+5+27=287
d+i=255
d=5*i+27

5*i+27+i=255
6*i=228
i=38
d=217

A:b=5 rest 27 ⇒ a=5b+27
Stim si ca a+b+5+27= 287 ⇒a+b=287-32=255
Folosim metoda figurativa
a /-----/-----/-----/-----/-----/....27...
b /-----/                                            suma 255
255-27=228 (suma a 6 segmente egale)
228:6=38 (un segment)
a=5*38+27=190+27=217
b=38
verificare 217:38=5 rest 27
