(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)的计算过程
(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)的计算过程

(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)的计算过程
(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)
=-2.5-2.7+1.6+2.7+2.4
=-2.5+(-2.7+2.7)+(1.6+2.4)
=-2.5+4
=1.5

(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)的计算过程是:

(-2.5)-(+2.7)-(-1.6)-(-2.7)+(+2.4)
原式=-2.5-2.7+1.6+2.7+2.4
=-2.5+(-2.7+2.7)+(1.6+2.4)
=-2.5+4
=1.5
