Hand signals Alfred hooper has an alternative hypothesis for the origin of the roman numeral system, for small numbers. 16 hooper contends that the digits are related to hand gestures for counting. For example, the numbers i, ii, iii, iiii correspond to the number of fingers held up for another to see. V, then represents that hand upright with fingers together and thumb apart. Numbers 610, are represented with two hands as follows (left hand, right hand) 6(v,i 7(v,ii 8(v,iii 9(v,iiii 10(V,V) and X results from either crossing of the thumbs, or holding both hands up in a cross. Another possibility is that each I represents a finger and V represents the thumb of one hand. This way the numbers between 110 can be counted on one hand using the order: ip, iipr, iiiprm, ivit, vt, vitp, viitpr, viiitprm, ixin, xn (PPinky, rring, mmiddle, iindex, tthumb nno fingers/Other Hand).

When the tallies were transferred analysis to writing, the marks were easily identified with the existing Roman letters i, v and. The tenth v or x along the stick received an extra stroke. This had flattened to Ʇ (an inverted T) by the time of Augustus, and soon thereafter became identified with the graphically similar letter. It was written variously as i or ic, was then abbreviated to or c, with c variant finally winning out because, as a letter, it stood for centum, shoprite latin for "hundred". The hundredth v or X was marked with a box or circle. Thus 500 was like a superimposed on a or, becoming d or Ð by the time of Augustus, under the graphic influence of the letter. It was later identified as the letter D; an alternative symbol for "thousand" was (I) (or ci or c and half of a thousand or "five hundred" is the right half of the symbol, I) (or i or and this may have been converted into. 15 This at least was the etymology given to it later. Meanwhile, 1000 was a circled or boxed X:, and by augustinian times was partially identified with the Greek letter Φ phi. Over time, the symbol changed to ψ and. The latter symbol further evolved into, then, and eventually changed to m under the influence of the latin word mille "thousand".
Every fifth notch was double cut. and every tenth was cross cut (x iiiiλiiiixiiiiλiiiixii. much like european tally marks today. This produced a positional system: Eight on a counting stick was eight tallies, iiiiλiii, or the eighth of real a longer series of tallies; either way, it could be abbreviated λiii (or viii as the existence of a λ implies four prior notches. By extension, eighteen was the eighth tally after the first ten, which could be abbreviated x, and so was xλiii. Likewise, number four on the stick was the i-notch that could be felt just before the cut of the λ (V so it could be written as either iiii or iλ (IV). Thus the system was neither additive nor subtractive in its conception, but ordinal.
Clock faces that use roman numerals normally show iiii for four oclock but ix for nine oclock, a practice that goes back to very early clocks such as the wells Cathedral clock of the late 14th century.

The Etruscans, for example, used, word and for i, v, x, l, c, and m, of which only i and X happened to be letters in their alphabet. Hypotheses about the origin of Roman numerals Tally marks One hypothesis is that the Etrusco-roman numerals actually derive from notches on tally sticks, which continued to be used by Italian and Dalmatian shepherds into the 19th century. 14 Thus, i descends not from the letter I but from a notch scored across the stick.
There are even instances of both forms appearing within the same document. While in standard usage subtractive notation is limited to use of "adjacent" numerals, so that 99 (for example) is written xcix, forms such as ic are not unknown. Xiix or iixx are sometimes used for "18" instead of xviii. The latin word for "eighteen" is often rendered as the equivalent of "twenty less two ( duodeviginti ) which may be the source of this usage. Sometimes v and l are not used, with instances such as iiiiii and xxxxxx rather than vi. 8 9 An inscription on Admiralty Arch, london. The number is 1910, for which mcmx would be more usual.

For example, the number 39 is xxxix, (three tens and a ten less one 246 is ccxlvi (two hundreds, a fifty less ten, a five and a one. As each place has its own notation there is no need for place keeping zeros, so "missing places" can be simply omitted: thus 207, for instance, is written ccvii (two hundreds, a five and two ones) and 1066 becomes mlxvi (a thousand, a fifty and.
