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 couldn't fins a solution using numebrs with 9 letters, but this one works for 10 letters.  I'm not sure it's the only solution.

Age = 24
House = 48
Sum = 72
Diff = 24
48/2 = 24
