You can use parenthesis () and braces {} but not brackets [] to separate subexpressions.
From time to time I am asked questions of number representations related to the above.
I'll be orginizing results in tables to keep them easily available. Normally, in this kind of
problems, allowed operations are different. I was limited by the JavaScript built-in parsing
facility. Thus, in the following pages I shall use operations listed below:
Remark: the whole part function is a powerful addition to the common arithmetic operations and factorials. This can be demonstrated by the surprising, but shallow, identity: [π][e] + [e] = [e][π] + [π].
Everyone can take part in filling these tables or creating new ones. I insist on one condition
though:
Tables may have gaps that would reflect on my current knowledge or cummulative time
investment into solving these puzzles. However, I am the only one allowed to create
gaps. All others either fill gaps or submit contiguous solutions for a series of numbers.
=4/.444...=9. For simplicity sake I'll write, say, 4/.(4) or with an overline, like, 4/.
