Răspuns :

A=15-3x6:(3x3x3:3+0:5)+30:(3:3+5) =(facem inmultirile si impartirile care putem)

A=15-18:(9x3:3+0)+30:(1+5)

A=15-18:(27:3)+30:6

A=15-18:9+5

A=15-2+5

A=13+5

A=18

B=25+[7x3x18:2-5x(5x4-36:3)] =

B=25+[14x18:2-5x(20-12)]

B=25+(252:2-5x8)

B=25+(146-40)

B=25+106

B=131

131+18=149

131-18=113

131x18=2358
