_________

a) [(45+5)×8-20×5):100 =

= (50×8-100):100 =

=  (400-100):100 =

= 300:100 =

= 3

______

c) 2×[90:2+(120:4-20)]×10 =

= 2×[45+(30-20)]×10 =

= 2×(45+10)×10 =

= 2×55×10 =

= 20×55 =

= 1100

______

b) 200-[(25+25×25):50]:13 =

= 200-[(25+625):50]:13 =

= 200-(650:50):13 =

= 200-13:13=

= 200-1 =

= 199

______

d) 2007+18:[2+(16-108:27):3] =

= 2007+18:[2+(16-4):3] =

= 2007+18:(2+12:3) =

= 2007+18:(2+4) =

= 2007+18:6 =

= 2007+3 =
