计算题如下：
1、(-8)-(-1)=(-8)+1=-7
2、45+(-30)=45-30=15
3、-1.5-(-11.5)=-1.5+11.5=10
4、-1/4-(-1/2)=-1/4+1/2=-1/4+2/4=1/4
5、15-[1-(20-4)]15-(1-16)=15-(-15)=15+15=30
四则运算的运算顺序：
1、如果只有加和减或者只有乘和除，从左往右计算。
2、如果一级运算和二级运算，同时有，先算二级运算。
3、如果一级，二级，三级运算（即乘方、开方和对数运算）同时有，先算三级运算再算其他两级。
4、如果有括号，要先算括号里的数（不管它是什么级的，都要先算）。
5、在括号里面，也要先算三级，然后到二级、一级。
