Basics:
A numeral is a symbol used to represent a number. (Our digits 0-9 are often called Arabic numerals.) Each letter used in Roman numerals stands for a different number:

A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.

You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.

You must separate ones, tens, hundreds, and thousands as separate items. That means that 99 is XCIX, 90 + 9, but never should be written as IC. Similarly, 999 cannot be IM and 1999 cannot be MIM.

I :The numeral one. 
II: is two,   III: is three. You seldom see IIII as 4, since IV can also mean 4, plus its shorter to write. 
V: The numeral 5. IV: is 4, VI: is 6, VII: is 7, VIII: is 8. 
X: The numeral 10. IX; is 9, XI: is 11, etc. 
L: The numeral 50. XL: would be 40. 
C: The numeral 100. Think of Century having a hundred years. C is short for the Latin word Centum. 
D: The numeral 500. 
M: The numeral 1000.
 
Sometimes you will see a numeral with a line over it. That means to multiply it by 1000. A numeral V with a line over it means 5000.
