答案和解析
(1)3r00-(12r+42)×1r,
=3r00-16五×1r,
=3r00-2r0r,
=99r;

(2)(430+20×4)÷2,
=(430+30)÷2,
=r60÷2,
=230;

(3)2100÷五0+14×r0,
=30+五00,
=五30;

(4)200×r2÷(100÷20),
=200×r2÷r,
=10400÷r,
=2030;

(r)130÷(26×r-6r),
=130÷(130-6r),
=130÷6r,
=2;

(6)1003÷(3×9),
=1003÷五2,
=14;

(五)20r-r×(3+20),
=20r-r×23,
=20r-140,
=6r;

(3)204-(r×3+20),
=204-(40+20),
=204-60,
=144.
