1)x :23=c rest c+19
x=23c +c+19
x=24c+19
x=M₂₄ +19
x-cel mai mare
x=24*9+19= 216+19= 235
2)a-suma numerelor
a:208=5 rest M₃
x=208*5 +M₃
x=1040 +M₃
x-cel mai mic => x=1040+3=1043
x=23c +c+19
x=24c+19
x=M₂₄ +19
x-cel mai mare
x=24*9+19= 216+19= 235
2)a-suma numerelor

1) a=23q+r q=19+r r<23
a=23(19+r)+r r<23=>r=22
a=23*19+23r+r
a=23*19+24r => a=23*19+24*22 =>a=437+528=>a=965
2) [tex]S_n[/tex] = ? daca n : 208 =5 (rest [tex]M_3[/tex] ) unde [tex]M_3[/tex] - multiplii lui 3
Stiim ca [tex]M_3[/tex] < 208 adica [tex]M_3[/tex] = {3;6;9;12;...;207} => [tex]S_n[/tex] = 208*5+(3+6+9+...+207)= 1040+3(1+2+...+69)= 1040+3* [tex] \frac{69*70}{2}[/tex] = 1040+3*69*35= 1040+7245=8285
a=23(19+r)+r r<23=>r=22
a=23*19+23r+r
a=23*19+24r => a=23*19+24*22 =>a=437+528=>a=965
