RATUNKU !!!!!!!!!!!!!!!

Answer 1

A ) . [(2+3): (3-1)-2]*(3-5) = [ 5 : 2 -2]*(-2) = (2,5 - 2)*(-2) = 0,5 * (-2) = -1

B ) . {[(4+2):(3-1)-(2+3)*(3-2)]*3}+7= [ (6 : 2 - 5*1)*3]+7=[(3-5)*3]+7=(-2)*3+7=-6+7=1

 

C ) . [(-3)+4*(6-3)]+(-3)*(6-4)=[(-3)+4*3]+(-3)*2=-3+12+(-6)=9-6=3

 

D ) . [(-3)+(-2)*(6+5)]-[6:(-2)+(-4)*2]=[(-3)+(-2)*11]-[(-3)+(-8)]=(-3)+(-22)-(-11)=-3-22+11= -25+11 = -14

 

[(4+3)*2*(5-3)]:[4+3*(3-2)]*(-1)= (7*2*2) : (4+3*1)*(-1)= 28 : (4+3)* (-1)=28 : 7 * (-1) = 4 *(-1) = -4
