Question

1. 2*(5-1):(4-2)=? 6*(7+13):(39-42)=? 2. [-3+(-2)*(6+5)]-[6:(-2)+(-4)*2]=? [(4+3)*2*(5-3)]:[4+3*(3-2)]*(-1) 3. 3*(-1)*(-2)*...0 -4*(-2)*...<0 prosze was pilne od tego zalezy moje zycie ;))

Answer 1

 2*(5-1):(4-2)= 2*4:2=8:2=4

6*(7+13):(39-42)=6*20: (-3)=120 :(-3)= -40

 [-3+(-2)*(6+5)]-[6:(-2)+(-4)*2]= [-3+(-2)*11)] - [-3 +(-6)]= (-3-22)-(-9)= -25+9= -16

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

 3*(-1)*(-2)*1.>.0

6>0

-4*(-2)* (-1)< 0

-8<0
