5.5*13.6-0.36*55怎么简便计算?

5.5*13.6-0.36*55怎么简便计算?
5.5*13.6-0.36*55
=5.5*13.6-3.6*5.5
=5.5*(13.6-3.6)
=5.5*10
=55

5.5*13.6-0.36*55
=55*1.36-0.36*55
=55*(1.36-0.36)
=55*1
=55

你好~
5.5*13.6-0.36*55
=5.5X13.6-0.36X(10X5.5)
=5.5X13.6-5.5X3.6
=5.5X(13.6-3.6)
=55
那块不懂请追问。

5.5*13.6-0.36*55
= 55* 0.1 *13.6-0.36*55
= 55 * 1.36 - -0.36*55
= 55* (1.36 - 0.36)
= 55*1
=55
