原式
=6.32x12+8.8x63.2
=6.32x12+8.8x10x6.32
=6.32x12+88x6.32
=6.32x(12+88)
=6.32x100
=632
或者
=6.32x10x1.2+8.8x63.2
=63.2x1.2+8.8x63.2
=63.2x(1.2+8.8)
=63.2x10
=632
=6.32x12+8.8x63.2
=6.32x12+8.8x10x6.32
=6.32x12+88x6.32
=6.32x(12+88)
=6.32x100
=632
或者
=6.32x10x1.2+8.8x63.2
=63.2x1.2+8.8x63.2
=63.2x(1.2+8.8)
=63.2x10
=632
