VA ROG AJUTATI-MA !!!!!
DAU CORONITA !!!!!

Answer 1

a) -23x(-15)+(-23)x5=
-23x(-15+5)=23*20=460

b) 3x(-7)+2x(-4)-(-5)x(-3)=
=-21-8-15=-44

c) (-3+5)x(-4+2)=
=2*(-2)=-4

d) -4+(-9)x(-5)=
=-4+45=41

e) (9-5)x(-3-5)x(-25)=
=4x(-8)x(-25)=800

f) 512x(-105)+205x512=
=512x(-105+205)=
=512x100=51200

g) 25x(-223)x(-8)-(-223)x(-199) =
=(-223)x[(25)x(-8)-(-199)]=
=(-223)x(-200+199)=
=-223

 h) 8888x(-296)+8888x196=
=8888x(-296+196)=
=8888x(-100)=-888800
