Brain Teasers and Logic Puzzles

Can you make nine out of l l l l l l by only adding 5 lines?

Asked by Anonymous

You need to add the lines in such a way that they SPELL "nine," not that they add up to make a total of nine lines. It's a trick question. Simply add a diagonal line from top left to bottom right to the first two vertical lines and you have the letter "N." Then leave the third vertical alone as it is already the letter "I." Then do the same thing you did to the first two lines to the fourth and fifth lines for the second "N." Finally, add three horizontal lines to the last vertical line to make the letter "E" and, shazam, you have N-I-N-E.

What are two ways of adding 89.5 to 1676.5 and two ways of subtracting 89.5 from 1676.5 but working out all four calculation from start to finish in Roman numerals?

Asked by Anonymous

The rules as we now know them today governing the Roman numeral system had absolutely nothing to do with the ancient Romans whatsoever because they were introduced during the Middle Ages long after the collapse of the Roman Empire but we can extrapolate from historical sources such as for instance 'History of Mathematics' volume 2 by David Eugene Smith first published in 1925 and ISBN 0486 204 308 that the ancient Romans would have probably worked out the given figures as in any of the following formats:-

MDCLXXVIS+LXXXVIIIIS = MDCCLXVI => 1676.5+89.5 = 1766

MDCLXXVIS+SXC = MDCCLXVI => 1676.5+(-0.5-10+100) = 1766

MDCLXXVIS-LXXXVIIIIS = MDLXXXVII => 1676.5-89.5 = 1587

MDCLXXVIS-SXC = MDLXXXVII => 1676.5-(-0.5-10+100) = 1587

Note that the Roman numeral for 0.5 is S and that in mathematics -(-0.5-10+100) changes to +0.5+10-100

What are the Roman numerals from 1 to 1 million?

Asked by Anonymous

The entire sequence would consume 83mb worth of characters.

The first 100 are as follows:

1-10: i, ii, iii, iv, v, vi, vii, viii, ix, x

11-20: xi, xii, xiii, xiv, xv, xvi, xvii, xviii, xix, xx

21-30: xxi, xxii, xxiii, xxiv, xxv, xxvi, xxvii, xxviii, xxix, xxx

31-40: xxxi, xxxii, xxxiii, xxxiv, xxxv, xxxvi, xxxvii, xxxviii, xxxix, xl

41-50: xli, xlii, xliii, xliv, xlv, xlvi, xlvii, xlviii, xlix, l

51-60: li, lii, liii, liv, lv, lvi, lvii, lviii, lix, lx

61-70: lxi, lxii, lxiii, lxiv, lxv, lxvi, lxvii, lxviii, lxix, lxx

71-80: lxxi, lxxii, lxxiii, lxxiv, lxxv, lxxvi, lxxvii, lxxviii, lxxix, lxxx

81-90: lxxxi, lxxxii, lxxxiii, lxxxiv, lxxxv, lxxxvi, lxxxvii, lxxxviii, lxxxix, xc

91-100: xci, xcii, xciii, xciv, xcv, xcvi, xcvii, xcviii, xcix, c

Thereafter, the sequence continually repeats, first prefixed with a 'c' until we reach 'cc', for 200. Then repeat again with another prefixed 'c' until we reach 'ccc' for 300. We prefix one more 'c' until we reach 'cccxcix' (399). 400 is represented by 'cd', which becomes the prefix for another sequence until 'cdxcix' (499). 500 is 'd', which begins a new repetition of all the numbers from 1-499, prefixed with 'd'. 999 is 'cmxcix'.

1000 is 'm', which begins the entire sequence again, until 'mm' (2000), and 'mmm' (3000). The last possible number is 'mmmcmxcix' (3999).

That's as far as we can go using this system (no symbol may repeat more than 3 times in succession). From this point on we must switch to the original symbols for 'm' and 'd' that begins with 'c|ᴐᴐc|ᴐc|ᴐ|ᴐ' (4000) and repeatedly counts from 1 to 999 using this prefix.

Under this system, 'm' is replaced with 'c|ᴐ' (1000) and 'd' is replaced with '|ᴐ' (500).

5000 is represented by '|ᴐᴐ' (the additional 'ᴐ' multiplies 500 by 10).

6000 is '|ᴐᴐc|ᴐ' (5000 + 1000).

7000 is '|ᴐᴐc|ᴐᴐ|ᴐ' (5000 + 1500 + 500). The additional 'ᴐ' in 'c|ᴐᴐ' adds 500 to 1000. An alternative would be to use the prefix '|ᴐᴐc|ᴐc|ᴐ' (5000 + 1000 + 1000), which is probably correct, but my program always subtracts the highest possible value, so I always use the former notation.

8000 is '|ᴐᴐc|ᴐᴐc|ᴐ|ᴐ' (5000 + 1500 + 1000 + 500) or '|ᴐᴐc|ᴐc|ᴐc|ᴐ' (5000 + 1000 + 1000 + 1000).

9000 is 'c|ᴐcc|ᴐᴐ' (10,000 - 1000).

10,000 is 'cc|ᴐᴐ'. Each extra 'c' and 'ᴐ' (together) multiply the value by a factor of 10. It's easier to think of the extra 'c' and 'ᴐ' symbols as ellipsis enclosing the value. This can be extended to give 'ccc|ᴐᴐᴐ' (100,000) and finally 'cccc|ᴐᴐᴐᴐ' (1,000,000).

To give an idea of this system, the final 100 numbers are as follows:

These symbols can be extended to multiply the value by a factor of 10, such that
