It's not really maths IMO since I think using 98 is cheating for instance, it's really (9 X 10 + 8), 10 not being allowed. So kids are not learning real maths, more arithmetic.
- lanna 10y agoThere is no script, he did it mostly by hand.
- aaron695 10y agoI would have thought that to be the fun bit! I think there was at least one script for some of the numbers, this I would have thought the most interesting, optimisation of the script and for all numbers and proving some numbers have no solutions([edit] possibly very hard) - "The author is thankful to xxxx in finding some difficult representations using computerized script."
- lanna 10y ago"some". In previous versions of the paper, he claims to have done everything manually: "To bring these numbers, thousands of combinations are considered without use of any programming language."
- adtac 10y agoI just wrote a tiny script that does this: https://github.com/adtac/123456789/blob/master/main.py https://github.com/adtac/123456789/blob/master/main.py
- thomasahle 10y agoHuh, he does 98 as 98=1×23+45+6+7+8+9. Or do you mean that 23 and 45 are cheating, because they are two digit numbers? I think they rules are quite well explained and followed.
