CCCIV
You would write it like this. CCCIV
100 = C (300 = 100+100+100 = CCC) 5 = V 1 = I (4 = 5-1 = IV) Answer: CCCIV
No person invented zero. However mathematicians in many cultures realized that in large numbers there had to be a placeholder for 'Empty" spaces (as an example the number 304 is really three values of a hundred + no vales of ten + four values of one). The Roman system of writing that as CCCIV got around the question by simply showing each number as a sum of other numbers (this made multiplication difficult)Various culture represented the "zero" values with 0, a blank space, or a dot (.). Today we have settled on the zero (0) as the representation of an empty value.
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
atomic number = number of proton in an element number of proton = number of electron mass number = number of proton + number of neutron therefore... atomic number = mass number - number of neutrons
A positive number. Positive Number x Positive Number = Positive Number Positive Number x Negative Number = Negative Number Negative Number x Negative Number = Positive Number
