In this lesson you will learn:

• Why Roman Numerals should be learned
• Where Roman Numerals are thought to have originated
• A fun mnemonic to remember the symbols and their value

Next

The Roman Numeral number system is restrictive because there are no 'place values' as we have with our Base 10 Arabic system.  Each symbol has a very specific value, and always has this value.

Because of this, we need to combine symbols together to create values that differ from the Symbols.

An example of this would be when we want to represent the value of twenty in Roman Numerals.  There is no symbol for 20, so how do we do this?

You are about to master converting Arabic Numbers to Roman Numerals, and Roman Numerals to Arabic Numbers with a focus on values that do not contain 4's or 9's!

Now that you know how to combine values to represent Roman Numerals, it is time to explore the numbers that contain 4's and 9's.

We have waited until now to work on these, as these numbers require the use of the only two rules you need to remember when working on Roman Numerals ...

1. The Subtractive Rule &
2. The 'Two-Up Rule'

Once you have mastered these two rules, there is NO number up to 4,999 that you cannot represent.  And for many, this is more than high enough, as the most common use for Roman Numerals is to represent years.

In this lesson you will master the five specific steps you must take when adding Roman Numerals without converting them to Arabic Numbers first.
