18.76-12.54+13.6
=18.76+13.6-12.54
=18.76+(13.24+0.36)-12.54
=18.76+13.24+0.36-12.54
=32+0.36-12.54
=32-12.54+0.36
=19.46+0.36
=19.82
=18.76+13.6-12.54
=18.76+(13.24+0.36)-12.54
=18.76+13.24+0.36-12.54
=32+0.36-12.54

18.76-12.54+13.6
=18.76+(13.6-12.54)
=18.76+1.06

或者
18.76-12.54+13.6
=18+0.76-12-0.54+13+0.6
=(18-12+13)+(0.76-0.54+0.6)
=19+0.82
=19.82
=18.76+(13.6-12.54)
=18.76+1.06
=19.82
或者
18.76-12.54+13.6
=18+0.76-12-0.54+13+0.6
=(18-12+13)+(0.76-0.54+0.6)
=19+0.82
=19.82
