Sums and Letters (Posted on 2005-04-27) Difficulty: 2 of 5
I wrote down five different two-digit numbers:

  • My age
  • My house number
  • The sum of those first two numbers
  • The difference between those first two numbers
  • Half of one of those first four numbers

I chose to write down the names of the numbers in letters rather than use digits (e.g. "thirty six").
Surprisingly, I noticed that each of the five numbers had the same number of letters in its name.

What were the last three numbers I wrote?

I adjusted my program and came up with 32, 49, 81, 17 and 64.  98 doesn't contain nine letters.  But 64 does and it's 2x32.
