9 & Mathematics

(0 评审)

把任意数字的个、十、百……位数字依次相加所得的数字不等于 9 的,大于 9 继续相加,

用最后加得的小于 9 的数字与其上个和相减所得的数字大于 9 的话,继续相加相减,最后的结果都会是 9!

22

- 4(2+2)

18

- 9(1+8)

= 9

1873

- 19(1+8+7+3)

- 10(1+9)

- 1(1+0)

= 9

3954230

26(3+9+5+4+2+3+0)

- 8(2+6)

18

- 9(1+8)

7468746746

59(7+4+6+8+7+4+6+7+4+6)

14(5+9)

……

大家可以随意选择数字尝试,电话号码、生日、纪念日……

这个规律 8 系 5 发现的,8 用崇拜 5 !

希望大家能够因为数学的微妙对它更感兴趣!
