1. History
- More than 2000 years ago, the Roman Empire conquered many European countries, and these countries adopted their language, and their numbers. But then the countries stopped using those numbers to use the Arabic numerals, the current one. But despite that, Roman numerals are still very important.
1. HISTORY
Some examples where we can see Roman numerals are this type of clock, the names of kings, for example Felipe VI and Felipe V, or when we talk about centuries, for example to say that we are in the 21st century. (XXI)

3. 7 LETTERS
To begin with, the Roman numerals are expressed by means of seven letters of the Latin alphabet, which are: I = 1 V = 5 X = 10 L = 50 C = 100 D = 500 M = 1,000
The same happens with the 90, you would have to subtract 10 from 100, XC
Once we have learned this, we can see that to form 6, we have to put 5 (V) and 1 (I) together, like VI. This is how you add, but when you get to 9, instead of putting VIIII, you have to take one from 10, that is, if putting the I behind is adding, you have to put an I in front. Type 1 minus 10, IX We also find that to put 20, we put XX, for 30 we put XXX, but for 40 we have to use the subtraction rule again, for 40 we do 50 minus 10, that is, XL

5. games
The first activity, to practice maths, is that we can play on "Roman Numerals & Numbers" The second activity that will be done on the next day, is to play our own bingo with roman numbers.
