简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.98)简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.98)简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.9

简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.98)
简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.98)

简便计算:(+0.02)+(-3.4)+(-0.6)+(+1.98)
式子变化得:【(+0.02)+1.98】+【(-3.4)+(-0.6)】=2+(-4)=-2

等于-2

(+0.02)+(-3.4)+(-0.6)+(+1.98)
=(0.02+1.98)-(3.4+0.6)
=2-4
=-2
