For 3762 + 8271 = ?, it would be 18 and 18, multiplied together is 324. Backwards, this is 423, which is what I answered. Let me state again that I am most likely an idiot, and by no means take responsibility for any wrong answers taken from this post.
Nice theory, but...
4 + 4 would then equate to 4 x 4 = 16. Reverse digits = 61!! The Conundrum states the answer is 8.
No, the answer lies in Base 9. Just as an additional quest, does anybody know the 'name' for base nine - ie Binary is base 2, octal is base 8, decimal is base 10, and hexadecimal is base 16. So what is base 9???
Anyway, thanks to Stapel (Eliz.) for pointing us in the right direction.
Perhaps in future, anybody who knows the answer should publish it in 100 point font, in bright red, highlighted in yellow, with a big arrow labelled "THIS IS THE ANSWER", YES THIS ONE HERE" because every week, even after correct answers are published, people come on and ask what the answer acrually is.
Just in case there is any douby the answer is definately 294,215,686,440,197,141,401..... or was that last weeks???
