The method for calculating the actual age with the last digit of the mobile phone circulating on the Internet is related to algorithms? Secret of age and mobile phone number
Who did find this? Accurate.
[1] check the last digit of your mobile phone number.
[2] Multiply this number by 2
[3] then add 5
[4] multiply by 50
[5] add 1763
[6] In the last step, use this number to subtract the year of your birth. Now you can see a three-digit number. The first digit is the last digit of your mobile phone number, followed by your actual age!

Blind eye, since you have provided your birth year, 2013-your birth year is your age.
In the previous section, we only wanted to keep the hundreds of digits at the end of your mobile phone and bring 2013.
Your mobile phone tail number is x
(2x + 5) * 50 + 1763 => 100x + 250 + 1763
The focus is here. 250 + 1763 = 2013,
Minus the date of birth...
This problem is no longer technical and has nothing to do with algorithms --!
This is the case.
