答案和解析
计算
l0-5l-l(-4)-(+6)l-l(-7.5)+2-(+5.5)l
=5-10-11
= -5-11
= -16
11/4-[(-0.5)-(-5/6)+(-3/4)+14/3]
=11/4-（-1/2+5/6-3/4+14/3）
=11/4-51/12
=33/12-51/12
= -18/12
= -3/2
l0-5l-l(-4)-(+6)l-l(-7.5)+2-(+5.5)l
=5-10-11
= -5-11
= -16
11/4-[(-0.5)-(-5/6)+(-3/4)+14/3]
=11/4-（-1/2+5/6-3/4+14/3）
=11/4-51/12
=33/12-51/12
= -18/12
= -3/2
