Former president Jimmy Carter (birth name James Earl Carter, Jr., born on Oct. 1, 1924, in Plains, Georgia) served as the 39th President of the United States between 1977 and 1981 [1]. In 1982, he established the Carter Center to participate in initiatives including monitoring international elections, fighting third world diseases and seeking international peace. Carter received the Presidential Medal of Freedom (highest honor for an American civilian) in 1999 and won the Nobel Peace Prize in 2002.

Last August, Carter announced that his recent liver surgery revealed that he has cancer in other parts of his body and that he will undergo treatment. I was saddened by this news because I always admired Carter for his decency and particularly, his lifelong commitment to humanity and genuine efforts to achieve peace all over the world.

This week, Thursday, Oct. 1, 2015 marks Carter’s birthday and he will turn 91. On this occasion, I constructed the following numerical brainteaser birthday gift for him:

  1. There is a secret code hidden in President Carter’s birthday. How so? Carter was born on 10-01-1924 or simply, 10011924. Split this number into numbers 1001, 1, and 924, and subtract the reverse of 924 (429) from 1001, yielding 572. The reverse of 572 is 275 and further subtracting 1 from 275 gives 274. What is the 274th day of 2015? (Answer: Carter’s 91st birthday, Oct. 1!) What is the 275th day of any leap (e.g., 2016)? (Answer: Again, Oct. 1st.)
  2. If numbers 1 to 26 are assigned to the letters of the English alphabet as A being 1, B is 2, C is 3, etc., the numbers assigned to the letters of “Jimmy” and “Carter” each add up to 70 and 65 respectively, and 70 plus 65 yields 135, a number representing “Jimmy Carter.” Note that Carter’s 91st birthday coincides with the 274th day of 2015 where 274 equals 2 times 137 and interestingly enough, these two primes differ by 135 (“Jimmy Carter”).
  3. Carter was born on the 275th day of 1924. If 275 is split as 27 and 5, the product of these two numbers yield 135 (“Jimmy Carter”). Also, the product of the digits of 275 yields 70, which coincides with the sum of the numbers assigned to the letters of “Jimmy.”
  4. President Carter’s birthday, Oct., 1, expressed as 1001 is a special palindrome number which equals the product of three consecutive primes, 7 x 11 x 13. Interestingly enough, digit 7 is the fourth prime number and if one replaces 7 with 4, 4 x 11 x 13 yields 572, with reverse 275 (Carter was born on the 275th day of 1924). In addition, President Carter’s new age 91 equals palindrome 1001 divided by palindrome 11, where 11 equals the sum of the left and right halves of 1001. Also, 11 represent the number of letters in “Jimmy Carter.”
Happy 91st birthday, Jimmy Carter and I hope you will get well soon so that you can continue your true leadership to make our world more safe and peaceful.
