Answer 1

Răspuns:

(423-21x12-90):(666-31x13-254)=

(423-252-90):(666-403-254)=

(171-90):(263-254)=

81:9=9

(995-61x16-1):(777-41x14-194)=

(995-976-1):(777-574-194)=

(19-1):(203-194)=

18:9=2

(56:7+8x6)-(204-81:9-156)=

(8+48)-(204-9-156)=

56-(195-156)=

56-39=17

(64:8+9x5)-(301-49:7-256)=

(8+45)-(301-7-256)=

53-(294-256)=

53-38=15

(108x71-51x150):2+72:9:4=

(7.668-7.650):2+8:4=

18:2+2=

9+2=11
