Question

calculati diferenta dintre produsul si suma nr x si y :
x=3z, y=t:6, z=5x(126-8x7:14)-210, t=60x25-[190x5-(4x35+27x14):7]x37:74

Answer 1

z=5x(126-8x7:14)-210=
 =5x(126-56:14)-210=
 =5x(126-4)-210=
 =5x122-210=
=610-210=400

t=60x25-[190x5-(4x35+27x14):7]x37:74=
=1500-[950-(140+378):7]x37:74=
=1500-[950-518:7]x37:74=
=1500-[950-74]x37:74=
=1500-876x37:74=
=1500-32412:74=
=1500-438=
=1062

x=3z=3*400=1200
y=t:6=1062:6=177
x+y=1200+177=1377
x*y=1200 *177=212400
x*y-(x+y)=212400-1377=211023
