Read Roman numerals to 1,000 (M) 10 - Reasoning

The task at hand involves reasoning with Roman numerals, a number system that was used in ancient Rome and is still occasionally used today. The problem statement presents a series of Roman numerals and asks the reader to determine the truth of a statement regarding their summation. The first example provided is XVIII (which represents 18) added to XII (which represents 12), which incorrectly totals to XXX (30). However, the correct sum of XVIII and XII is XXX (30). The question then asks whether it is true or false that the same Roman numerals (XVIII and XII) add up to 40, which is false as they add up to 30, as previously established.

Furthermore, the reader is challenged to write two Roman numerals that together would equal 45. An example of a correct sum is given: XXX (30) plus XV (15) equals XLV (45). This exercise tests the reader's understanding of Roman numerals and their ability to perform basic arithmetic operations using this ancient numerical system. The repeated true or false question about the sum of XVIII and XII aims to reinforce the concept that their sum is not 40 but 30. The activity serves as a practical application of reading and understanding Roman numerals up to 1,000 (M) and their place value within the number system.
