Question

Calculeaza:50:(3x3-3:3-3x3:3)= (5x8+14:7):(3x3-14:7)= 2x3x5+60:10:6-31= 16-16:8+(16-16):8+99= (100-60-6x5)x5+(10-6:3):8= 45:5+54:6-(54+45):(4+5)=

Answer 1

50:(3x3-3:3-3x3:3)=
50:(9-1-3)=
50:5=10
...................................
(5x8+14:7):(3x3-14:7)=
(40+2):(9-2)=
42:7=6
............................................
2x3x5+60:10:6-31=
30+1-31=0
.................................................
16-16:8+(16-16):8+99=
16-2+0+99=113
.....................................
(100-60-6x5)x5+(10-6:3):8=
(40-30)x5+(10-2):8
10x5+8:8=
50+1=51
..............................................
45:5+54:6-(54+54):(4+5)=
9+9-108:9=
18-12=6
