算出您合适求婚年龄的方程式--math formula that predicts you proposal age

First the mathematicians worked out a fiendishly complex equation: 
∑ (n-k)  (n-k-1)  (n-k-2) … (n-k-r+2) x       k        x   (1)
       n       (n-1)    (n-2)        (n-r+2)        (n-r+1)      (r-1)

 

STEP-BY-STEP GUIDE

Choose the oldest age by which you want to get married, for example 39.  Call this number 'n.’

Decide the earliest age at which you'll start to consider women as potential wives, for example, from 20 onwards. This number becomes 'p'.

Subtract 'p' from 'n' (20 from 39) then multiply the result by 0.368. 

This gives you 6.992, which you should add to your minimum age (20). 

The result of 27 (more or less) is your Optimal Proposal Age.
