Calculează:
a) (18 + 2 * 7): (12: 2 +8:4)
b) 42:7 + (6 + 6): 2-24 : (5 + 3)
c) 24 - 24:3x (72:9-2x3): 45. e) (25 + 20): 5 - (19 + 5): 8
c) 36: 6+4 2 x 5 - (20 - 12:3) f) 10 + (10:10 + 10) - (10 x 1 + 10)​

Answer 1

Răspuns:

a) (18+2*7):(12:2+8:4)=(18+14):(6+2)=32:8=4

b)=6+12:2-24:8=6+6-3=9

C)=24-24:3*(8-6):45=24-24:3*2:45=24-8*2/45=24-16/45=1064/45

E)=45:5-24:8=9-3=6

D) =6+210-(20-4)=6+210+16=200

F)=10+(1+10)-(10+10)=10+11-20=1
