IMM-IC = CMM because it is the same as -1+2000--1-100 = 1900
Remember that in maths a minus minus is equal to a plus.
So --1 = 1
In today's terms 1999 and 99 in Roman numerals are MCMXCIX and XCIX respectively. MCMXCIX - XCIX = MCM (1000-100+1000 = 1900) Alternatively in the days of the Roman Empire the Romans themselves would have probably wrote out 1999 and 99 as IMM and IC respectively. IMM - IC = CMM (-100+2000 = 1900)
99 = IC (-1+100) But today's conversion of 99 into Roman numerals is XCIX However, the Romans themselves would have probably wrote out the number 99 as LXXXXVIIII which then can be simplified to IC
ic
Presumably you'r asking the question: What does ic represent in Roman numerals? The lower case numerals for IC is ic, they both have the same numerical value and that is 99.
C is 100
Under todays modern rules governing the Roman numeral system, intoduced during the Middle Ages, the equivalent of 99 converted into Roman numerals are XCIX which restricts their ability for constuctive interaction with themselves or other numerals. But there is historical evidence to show that the ancient Romans would have worked out the equivalent of 99 as LXXXXVIIII and then abridged it to IC, which means 100-1, in written format thus facilitating operations of multiplication as follows:- Note: -IC*-IC has the same product as IC*IC So: -I[IC]+C[IC] = +I-C-C+(X) = CC(X)I or as (IX)DCCCI => 9801 Note: numerals within brackets of (n) indicate multiplication by a 1000
IC (C with line over it).
If you mean IC = 100-1 in Roman numerals then its full form is LXXXXVIIII = 99 Note that in todays modern configuration of Roman numerals 99 is now considered to be XCIX
The above numbers converted into Roman numerals are IX, XC, M, CM and XI respectively and the Romans would have probably added them up in the following fashion:- IX+XC = IC IC+M = IMC IMC+CM = IMM IMM+XI = MMX Hindu-Arabic conversion:- 9+90 = 99 99+1000 = 1099 1099+900 = 1999 1999+11 = 2010 For more complicated calculations the Romans would have used an abacus counting device.
Yes and Latin the word for IC is 'undecentum' meaning one from a hundred. IC is a simplification of LXXXXVIIII because by placing I to both sides of these numerals they work out as IC (-1+100 = 99) But under today's rules 99 in Roman numerals are XCIX
The numbers of 9, 90, 900 and 1000 converted into Roman numerals are IX, XC, CM and M in their simplified format and can be added up in the following manner:- IX+XC = IC (99) IC+CM = IM (999) IM+M = IMM (1999) When added up in their expanded format the result is the same because:- VIIII+LXXXX = LXXXXVIIII = IC when simplified LXXXXVIIII+DCCCC = DCCCCLXXXXVIIII = IM when simplified DCCCCLXXXXVIIII+M = MDCCCCLXXXXVIIII = IMM when simplified The Romans would have used an abacus counting device to calculate the above numerals and probably simplified them in written form as detailed above. Today we don't calculate Roman numerals in the way that the Romans actually did themselves because under today's rules governing the Roman numeral system that were introduced during the Middle Ages the number 1999 is notated as MCMXCIX in Roman numerals. Roman numerals: M=1000, D=500, C=100, L=50, X=10, V+5 and I=1
Today we would convert the above numbers into Roman numerals as IX, XCIX, CMXCIX and MCMXCIX respectively which makes any form of mathematical operations with them almost impossible. But during the Roman era the equivalent of 9 99 999 and 1999 were probably wrote out in a simplified format of IX, IC, IM and IMM respectively which makes addition straightforward as follows:- IX+IC = CVIII (9+99 = 108) CVIII+IM = MCVII (108+999 = 1,107) MCVII+IMM = MMMCVI (1,107+1,999 = 3,106) So when added together the answer is: MMMCVI which is the equivalent of 3,106
