(8+16):4=
15+5+10):5=             
5.sa se efectueze: 
94-6x7+9x3=
(64+24):8+10:5=
3x(23+22)-45:9=
9x9-6x6+42:6=
(72:8+7):4+81:9=
36:(3x2+9:3)+(7x3-12:2):(6x5-15)=

Answer 1

(4+8+18)/2=
30/2=15
4/2+8/2+18/2=
2+4+9=15

(6+12+18+24)/3=
60/3=20
6/3+12/3+18/3+24/3=
2+4+6+8=
6+14=20

(8+16)/4=6
8/4+16/4=
2+4=6

(15+5+10)/5=
30/5=6
15/5+5/5+10/5=
3+1+2=6

94-6*7+9*3
94-42+24=
52+24=76

(64+24)/8+10/5
64/8+24/8+10/5=
8+4+2=14

3*(23+22)-45/9=
3*23+3*22-45/9=
69+66-5=
135-5=130

9*9-6*6+42/6=
81-36+7=
45+7=52

(72/8+7)/4+81/9=
(9+7)/4+9=
16/4+9=
4+9=13
