一道初一题.(脱式计算)谢谢-7+3.54+(-4.52)-2-(-16.52 )-5.54===
原式=-7+3.54-4.52-2+16.52-5.54
=(3.54-5.54)+(16.52-4.52)-2-7
=-2+12-2-7
=1

直接去括号啊,初一课本,第二章有详细的去括号法则

-7+3.54+(-4.52)-2-(-16.52 )-5.54
=-7+3.54-4.52-2+16.52 -5.54
=-7-2+3.54-5.54+16.52 -4.52
=-9-2+12
=1

=-7-2+3.54-5.54-4.52+16.52
=-9-2+12
=1

-7+3.54+(-4.52)-2-(-16.52 )-5.54
=-7+3.54-5.54-2+16.52 -4.52
=-11+12
=1

=-3.46-4.52-2+16.52-5.54
=-9.98+10.98
=1

=(-7-2)+(3.54-5.54)-(4.52-16.52)
=-9-2+12
=1
