Hint: So, basically we are asked to convert XXVI into Hindu-Arabic numeral form. According to the Roman numerals, I denotes 1, V denotes 5, X denotes 10 and L denotes 50. Remember that if a roman numeral has a prefix as the one step lower numeral, i.e., L can only be preceded by X, V can only be preceded by I, however, the exception to this is X, which can be preceded by both I and V then the preceding numbers is subtracted from the last number. For example: IV is 5-1=4. So, use these concepts to reach the answer to the above question.
Complete step-by-step answer:
Let us start the solution to the above question by knowing some rules of Roman numerals. According to the Roman numerals, I denotes 1, V denotes 5, X denotes 10 and L denotes 50. Remember that if a roman numeral has a prefix as the one step lower numeral, i.e., L can only be preceded by X, V can only be preceded by I, however, the exception to this is X, which can be preceded by both I and V then the preceding numbers is subtracted from the last number. For example: IV is 5-1=4. So, use these concepts to reach the answer to the above question. Also, unlike the standard number system, Roman numerals don’t have place values, rather all the digits/numbers are added to get the value of the number. For example: LX is 50+10=60.
Now let us move to the conversion of XXVI. As none of the symbols is preceded by a step lower numeral, we will directly add the values of the symbols to convert it to Hindu-Arabic numerals.
So, XXVI=10+10+5+1=26.
Therefore, the Roman numeral XXVI is 26 in Hindu-Arabic system.
Note: It is important that you know the meanings of different symbols in Roman numeral system. It is also seen that students make a mistake by comparing the Roman numeral system with the Hindu-Arabic system, due to which they assign place values to the symbols which is not correct in Roman numeral system.
