Demystifying the Roman Number System
The best thing about these ancient numbers is the fact that they only require a few fixed rules for you to solve any problems. Here are some basics of this system of notation:
- Seven alphabetical letters are used in this ancient mathematical system. They include I, V, X, L, C, D, and M each representing a number. Letter I is equal to number 1, V means 5, X =10, L means 50, C =100, D = 500 and M is equivalent to 1000.
- A bar over a letter multiplies it by 1000, for example X̅ =10,000.
- If one letter is immediately followed by one of equal or lesser value the two are added to get the total sum represented.
- If a letter is followed by one of higher value, the first is subtracted from the second to get the total sum. For example, IV=4 because V=5 and it is greater than I=1.
- You cannot have more than three similar numbers following each other in any combination.
With these rules in place, it is now easy to learn how to go about calculating any problem presented. Some of the steps you can follow to ensure success include:
- Regular practice: It might sound like a cliché but practice makes perfect. As such, you need to utilize resources available such as online tests as much as possible because they enable you to interact more closely with these rules.
- Group revision: It is important to work in groups when working out Roman number problems. This ensures that different people bring something to the table and the learning process becomes interactive.
- Setting own combinations: As you prepare, try to create as many unique symbol combinations as possible as this helps your mind to be ready to solve any problem.
With this in mind you can now go out boldly and tackle any interview as Roman numbers will now be a piece of cake for you.
