D:I=C , +R

D=I*C + R

R < I
I=C=7      =>R={0,1,2,3,4,5,6}

1)R=0  =>D=7*7+0=49+0=49

2)R=1  =>D=7*7+1=49+1=50

3)R=2  =>D=7*7+2=49+2=51

4)R=3  =>D=7*7+3=49+3=52

5)R=4  =>D=7*7+4=49+4=53

6)R=5  =>D=7*7+5=49+5=54

7)R=6  =>D=7*7+6=49+6=55

D={49;50;51;52;53;54;55}

Stim ca Deimpartitul=Imartitorul*Catul +restul ..
0 ≤ restul ≤ impartitorul care este 7 ⇒ Restul mai mic ca 7
si are valorile : 0,1,2,3,4,5,6...
D=7*7+0=49
D=7*7+1=50
D=7*7+2=51
D=7*7+3=52.......D=7*7 +6=55  ...de unde ⇒D ∈ 49,50,51,52,53,54,55
