@=91


575-bx32-45=50
575-bx32=50+45
575-95=bx32
480:32=b
B=15


C-(600-315:9)=335
C-(600-35)=335
C-565=335
C=335+565
C=900


(100xd-110):39=10
100xd-110=10x39
100xd=390+110
100xd=500
D=500:100
D=5


20xe-(1950+550):100=6175
20xe-2500:100=6175
20xe=6175-25
20xe=6150
E=6150:20
E=307,5

35xf+(800-752:4):2=551
35xf+(800-188):2=551
35xf+612:2=551
35xf+306=551
35xf=551-306
F=245:35
F=7



G:25+(100-1632:51)x2=286
G:25+(100-32)x2=286
G:25+68x2=286
G:25+136=286
G:25=286-136
G=150x25
G=3750


244-hx5+(300-6x16):4=255
244-hx5+(300-96):4=255
244-hx5+204:4=255
244-hx5+51=255
244-hx5=255-51
244-204=hx5
40=hx5
H=40:5
H=8
