Put it away Gwenick.
You're not funny and you're not clever and Sparkler 1 should pick herself off the floor and be quiet.
misdee:
You seem to think I am wrong when patently I am not.
Your number begins with 13.
I only have a two digit memory.
Two hands, two feet, two digit memory.
But, lo and behold when we take your number:
13988
add them all up 1+3 = 4 plus 9 = 13 plus 8 = 21 plus another 8 equals 29 !!!!
And the reverse it and subtract them: 9 -2 = ?????
7
So, with my two guesses, not only did I get my full two digit memory allocation completely correct, but I also deduced the sum differential with my second guess.
I'm incredible.
Mad ? You wanna try that marmitey one. Proper Bonkerz.
