5.6x69.32+138.64x0.05+693.2x0.43
=5.6x69.32+69.32x2x0.05+69.32x4.3
=(5.6+2x0.05+4.3)x69.32
=10x69.32
=693.2
=5.6x69.32+69.32x2x0.05+69.32x4.3
=(5.6+2x0.05+4.3)x69.32

原式=5.6*69.32+（69.32*2）*0.05+（69.32*10）*0.43
=5.6*69.32+69.32*0.1+69.32*4.3
=69.32*（5.6+0.1+4.3）
=69.32*10
=693.2
=5.6*69.32+69.32*0.1+69.32*4.3
=69.32*（5.6+0.1+4.3）
=69.32*10
=693.2

5.6×69.32+69.32×2×0.05+69.32×0.43×10
=69.32×(5.6+0.1+4.3)
=69.32×10
=693.2
=69.32×(5.6+0.1+4.3)
=69.32×10
=693.2
