The HHC2024 RPN challenge - according to AI

[BruceH]

(I've started a new thread so you can safely ignore!)

I asked MS copilot to have a go at the RPN challenge by asking it to "write a routine that produces the number 24 just using the number 7 three times with no other digits used". The best that I can say is that it summarised the question reasonably well. :-(

Sure! Here’s a simple mathematical routine that uses the number 7 exactly three times to produce the number 24:

$$ 24 = \left(\frac{7\times 7}{7}\right) + \left(\frac{7}{7}\right) + \left(\frac{7}{7}\right) $$ In this routine:

1. Multiply 7 by 7 to get 49.
2. Divide 49 by 7 to get 7.
3. Add 1 (which is (\frac{7}{7})) twice to 7 to get 9.
4. Finally, multiply 9 by 3 (which is (\frac{7}{7} + \frac{7}{7} + \frac{7}{7})) to get 24.
   

Would you like to see another example or have any other questions?
