a) (27×125)+(49×104)=3375+5096=8471
b) (90:9)+(10×9999)=10+99990=100000
c) (102×32×12)+(39×1000)=39168-39000=168
d) (150×4)+[(150+4) ×100+(150+4) ×10]=600+(15400+1540)=600+16940=17540
A) 27+125=152
104x49=5096
B)90:9x10+9100=9200
C)102-32=70
12-3=9
D)produsul numerelor=150x4=600
Suma=150+4=154
Inzecitul sumei=154x10=1540
Insutitul sumei =154x100=15400.
600+1540+15400=17540
