Va rog, calculele sa fie desfasurate.

Answer 1

7000-(356 x 5 :10+17x100) x 3 + (4000 : 100 :5 x 9)=

7000-(178+1700) x 3 + (8 x 9)

7000- 1878 x 3 + 72

7000-5634+72

1336+72

1438

(806-588:4:7x15+100:10)x67-24x7+3=

(806-147:7x15+10) x 67-168+3

(806-21 x 15+10) x 67-168+3

(806-315+10)x 67-168+3

501x67-168+3

33567-168+3

33402

(854-65x2+500:100)x(360-50x6-68:4)+152=

(854-130+5)x(360-300-17)+152

729x43+152

31347+152
