Răspuns :
a - ( c - b ) = ???
_____________
a = 904 - 739
a = 165
b = 165 : 3
b = 55
c = 55 × 4
c = 220
____________
165 - ( 220 - 55 ) =
165 - 165 = 0

____________
165 - ( 220 - 55 ) =
165 - 165 = 0
a= 904 - 739 = 165
b= a : 3 b= 165 : 3 = 55
c= 4b c= 4×55 =220
a - ( c - b ) = 165 - ( 220 - 55 ) = 165 - 165 =0
b= a : 3 b= 165 : 3 = 55
c= 4b c= 4×55 =220
a - ( c - b ) = 165 - ( 220 - 55 ) = 165 - 165 =0
