HAPPY 95TH BIRTHDAY, NELSON ROLIHLAHLA MANDELA

South African anti-apartheid revolutionary and former President Nelson
Rolihlahla Mandela was born on Thursday, July 18, 1918 and this
Thursday, July 18, 2013 will mark his 95th birthday. In his honor, I
constructed the following numerical birthday brainteasers as a
birthday gift for him.

1. Mandela's current age 94 is special because it underscores the 94th
year of the 20th Century (that is, 1994) when Mandela became the
President of South Africa.

2. In addition, one less than twice 94 yields 187, his birth date,..
18 July.

3. Also, this year's number 2013 equals 33 x 61 where 33 plus 61 equals 94.

4. The full date number of Mandela's 95th birthday can be expressed as
18-7-2013, or simply, 1872013. This date is also the first day of the
96th year in Mandela's life. Interestingly enough, 1872013 equals 11 x
13 x 13 x 19 x 53 where the sum of the prime factors 11, 13, 19 and 53
equals 96! In addition, if numbers 1 to 26 are assigned to the letters
of the English alphabet in alphabetical order as A being 1, B being 2,
etc., the sum of the numbers assigned to the letters of Mandela's
birth name, "Rolihlahla" coincides with 96! Wow!

5. Also, reverse of Mandela's new age 95 is 59, a prime number.
Interestingly enough, prime 59 and the next two primes 61 and 67 add
up to Mandela's birth date 187.

6. Mandela's 96th birthday in 2014 will also be special since 96
represent his birth name, "Rolihlahla!"

7. Mandela's 97th birthday in 2015 relates to his name "Nelson"
because reverse of 97, which is 79, equals the sum of the numbers
assigned to the letters of "Nelson."

8. Mandela's 98th birthday in 2016 is also special because 98
represent two of the alternating digits of Mandela's birth year, 1918.
Also, 18 July is the 200th day of 2016 where 200 = 4 x 50 where 50
equals the sum of the numbers assigned to the letters of "Mandela."

9. Mandela's 99th birthday in 2017 will also be unique since twice 99
plus one yields 199 and coincidentally, the 199th day of 2017 is
Mandela's birth date, 18 July!

10. Mandela's 100th birthday in 2018 is also special since twice 100
minus one result in 199 and again, the 199th day of 2018 is his birth
date, 18 July!
