introducem intregi in fracti
1109/29+[41/3+35/6-51/9-(361/72-221/72-)]=
1109/29+[41/3+35/6-51/9-140/72]=
aducem la acelas numitor adica amplificam
4436/360+[4960/360+2100/360-2040/360-(1805/360-1105/360)=
daca avem acelas numotor putem sa nu. l mai scriem
4436+[4960+2100-2040-(1805-1105)=
facem calculul din paranteza rotunda
4436+(4960+2100-2040-700)=
4436+(7060-1240)=
4436+5720=10156
TE ROG DA. MI COROANA CA TE. AM AJUTAT
