The history of numbers is very interesting as they help us represent quantities and buy them without having to need the objects in front of us. In ancient times, coins didn’t exist and trade was based on barter, or exchanging goods. Because of this, the quantities we worked with were very small and could only be represented by small objects like pebbles.Although they invented numbers in the past, history needed a concrete number to center around. After all, how could we represent quantity when we have nothing at all?

That’s how zero, a very special number, was created.Later, they created many more numbers of various types. Today, we will learn about two types: cardinal and ordinal numbers.


We use cardinal numbers to count because they represent the quantity of elements there are.They start with the number 0, and continue with one, two, three, four. So on and on, but if you want to learn the first numbers, you can watch one of our videos. This video is a song, but careful, it’s very catchy! You won’t be able to get it out of your head!


Ordinal numbers are different because we use them to order and indicate position within a group. In this case, starting with zero doesn’t make sense, so we start with 1. In the case of ordinals, we change the name of numbers, in addition to accompanying them with the symbol ºFor example: the number one will be called first, two will be second, then third, fourth, etc.
