Answer 1

7*3+2*9-30:3= 21+18-10=29
(24:4-3)*9+27=(6-3)*9-27=27-27=0
(30-20:4):5=(30-5):5=25:5=5
(36:6+42:7)-4*2=(6+6)-8=12-8=4
(90:9-40:4)*10=(10-10)*10=0*10=0
(6*2+4*0):4=(12+0):4=12:4=3
(4+4*4-4):4=(4+16-4):4=16:4=4
(15+18:9+13):10=(15+2+13):10=(17+13):10=30:10=3
32:4+(15:5+72)=8+(3+72)=8+75=83
24:8+32:4+79=4+8+79=91
(80:10-2:2)=8-1=7
