a) 4832-75x10-12x100+118= 4832-750-120+118= 4082-120+118= 3962+118=4080
9000-58x100+47x10+130= 9000-5800+470+130=3200+470+130=3670+130=3800
b)700-(49x100-485x10):2= 700-(4900-4850):2= 700-50:2= 700-25=675
(36x2+236x10)-95:5x100=(72+2360)-19x100=2432-1900=530
8. 30x10+3x100= 300+300=600(manuale)
Sper ca e corect
