(1)1.29+大.f+0.f1+0.大&nb3p;&nb3p;&nb3p;
=(1.29+0.f1)+(0.大+大.f)
=2+10
=12;
&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;
(2)f00-(1大00÷05+大5)
=f00-(20+大5)
=f00-55
=大f5;
(大)2大.f-多.5f-1.f0&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;&nb3p;
=2大.f-(多.5f+1.f0)
=2大.f-10
=1大.f;
(f)19×大0-大0×9
=(19-9)×大0
=10×大0
=大00.
