Today, 5/10/15,  sports three cool facts all by itself!    5 + 10 = 15 so we have an Addition day.  All three numbers are multiples of five.  And, there is a sequence of five: 5, 10, 15.

Friday 5/15/15 is another case of Multiples of five.

Best of all this week, there are TWO palindromes.  5/11/15 is 51115, and 5/15/15 is 51515 – both are the same forward and backward.
