Explicație pas cu pas:
(36:a+63:9):2=8
(36:a+7):2=8
36:a+7=8x2
36:a + 7 = 16
36 : a = 16 -7
36 : a = 9
a = 36 : 9
a = 4
B+149+[(72:8+28:4):4]=396
B+149+[(9+7):4]=396
B+149+(16 : 4)=396
B+149+ 4 =396
B+153 =396
B = 396 - 153
B = 243
93-(85-9x9+5x8)-c=5x6+1
93-(85-81+40)-c=30+1
93-(4+40)-c=31
93 - 44 - c = 31
49 - c = 31
c = 49 - 31
c = 18
(242+360:10-214):(80:5-4x2)x d=1000
(242+36-214):(16-8)x d=1000
(278 - 214) : 8 xd = 1000
64 : 8 xd = 1000
8xd = 1000
d = 1000 : 8
d = 125
