Question

Calculati: [7-5*(2-3)]*(6-8)= -3-10*[362-10*(-24-2*3)]= (-5)*(-8)-4*10= (-1)*(-2)+3*(-6)= 2*(-3)*4-(-3)*(+4)=

Answer 1

 [7-5x(2-3)]x(6-8)= [7-5x(-1)]x(-2)=(7+5)x(-2)=12x(-2)=-24

-3-10x[362-10x(-24-2x3)]=-3-10x[362-10x(-24-6)]=
-3-10x[362-10x(-30)]=
-3-10x[362+300]=
-3-10x662=-3-6620=-6623

(-5)x(-8)-4x10=40-40=0

(-1)x(-2)+3x(-6)= 2-18=-16

2x(-3)x4-(-3)x(+4)=-24+12=-12
