Many Happy Returns to Each and All!
You actualy remind me of some of the maths problems we were given at school:
"a) robbie is older than saltysplash by half of the difference in age between dOmokun and saltysplash.
b) robbie is 36 years older than dOmokun.
c) If saltysplash is 51, how old are robbie and dOmokun?"
d) dOmokun is the youngest.
At the time, it often seemed like:
If DaveB lives in the UK, how many children does TSR2 have?
