a=I---I+7
b=I---I
-> b=(27-7):2=20:2=10;
a=10+7=17
P: 17+10=27;
17-10=7.
b=I---I
-> b=(27-7):2=20:2=10;
a=10+7=17
P: 17+10=27;
17-10=7.
I = |_____|
II= |_____|..+7..|
I + II = 2*|_____|+7 = 27
2*|_____|=20
|_____|=10
deci: nr.I=10 si nr.II=17
II= |_____|..+7..|
I + II = 2*|_____|+7 = 27
2*|_____|=20
|_____|=10
deci: nr.I=10 si nr.II=17
