The number one million can be presented by 2 digits : 1000000,
i.e. a chain of 7 digits.
Another possibility is 1000
2. 3 distinct digits, 5 characters. I
You are requested to express one million, using
a single digit d plus some operators creating a chain of n characters ( digits and operators).
What digit is your choice and how low is the minimal n?
a). The permissible operators are :
+ - * / and ^.
b). Sqrt and ! are allowed as well.”
.
REM: count digits and operators only, ignore ^, concatenation and brackets; e.g. (77-7)/7 is counted as 6.
(In reply to
Best known of each digit by Jer)
Four remarks .
i.
Part a OK.
Part b improved:
3,8: (3*3+3/3)^3!
4,9: (4+4+sqrt4)^(4+sqrt4)
9,8: (9+9/9)^((sqrt9)!)
ii. Lord’s use of ! as symbol of derangement is allowed, but not necessarily needed.
iii. IMHO <I>curate</I> is too pompous, maybe you’ve intended “created”...
iv. I wonder, why no one rates this puzzle, I think it is challenging, triggering debate and for me the only feedback to find out if it is wanted.
