Teen-aged Eritrean, Jemal Abraha, has developed a mathematical theory that associates a person’s phone number with their age, awarding him a signing fee of $30 million dollars to work with Apple after he graduates.

Take the last digit of your phone number.
Multiply it by two.
Add five.
Multiply the answer by 50.
Add 1,766.
Finally, subtract your date of birth.

Your answer should be a three-digit number. Take a look at the last two digits.

They reveal your current age or, if your birth date has passed this year, your age at the beginning of the year.
