Numbers are undoubtedly one of humanity's greatest creations. The story of their origin stems from the human need to count, measure, and represent quantities. Since ancient times, people have needed to keep track of their possessions—and that is how the first counting systems were born.
Ancient shepherds, for example, used pebbles to represent the number of animals in a flock: one pebble for each animal. This simple idea gave rise to the concept of numbers—abstract mathematical objects used to describe quantity, order, and measurement.
In this video, you will learn: How the need to count and represent quantities arose; The earliest forms of counting and umerical recording; What a number is and its role in mathematics;
Why the invention of numbers was a major milestone in human history.
Uma das maiores criações da humanidade é, sem dúvida, os números. A história da criação dos números surgiu da necessidade humana de contar, medir e representar quantidades. Desde os tempos mais antigos, o homem precisou registrar o que possuía — e foi assim que nasceram os primeiros sistemas de contagem.
Os pastores da Antiguidade, por exemplo, usavam pedrinhas para representar o número de animais de um rebanho: uma pedrinha para cada animal. Essa simples ideia deu origem ao conceito de número, um objeto abstrato da matemática usado para descrever quantidade, ordem e medida.

00:05In our daily lives, we deal with numbers all the time.
00:11It's highly unlikely that you'll go a single day without actively using them.
00:15For that very reason, we consistently use the familiar digits of the widely recognized Indo-Arabic numeral system.
00:22Numbers have been an integral and fundamental part of people's daily lives for countless millennia.
00:28But it's important to note that not all numbering systems are exactly like the familiar one we use every single day.
00:35Indeed, numbers are a deeply ingrained and essential component of people's existence and daily routines.
00:42They're present at home, at work, during leisure, at the supermarket, at the market, at school, in games, and so on.
00:51And quite often, we don't even truly realize it.
00:54What's incredibly interesting to consider is that numbers are extensively used for a multitude of significant purposes.
01:02For precise counting, for systematic ordering, for accurate measuring, for secure coding, and for many, many other essential applications.
01:11And now I would genuinely like to know a little bit more about you.
01:14How exactly are numbers prominently present in your everyday life?
01:19And also, for example, in what everyday situations do you use numbers?

01:34And now, let's get started.
01:38I'm going to tell you a story.
01:40A very long, long time ago, in ancient times, to accurately know the precise number of sheep he possessed,
01:47a diligent shepherd would carefully set aside a small pebble for each individual sheep as he gently led them out to peacefully graze.
01:55When bringing the entire flock back home, he would then meticulously remove one pebble for each and every sheep he successfully found and accounted for.
02:05Each pebble taken away corresponded to one sheep.
02:09It was by comparing quantities like this that humans learned to count.
02:14On one side, we have the number of pebbles.
02:17On the other, the number of sheep.
02:19From this, an idea common to both groups he was comparing emerged.
02:23First, the number.
02:26People also used to record quantities by, for example, tying knots in ropes or making marks on pieces of wood or bone.
02:35Each knot and each mark on the wood or bone corresponded to one item in the quantity they wanted to count.
02:44Unfortunately, very few of these records exist today.
02:48So folks, that's where we'll end today's lesson.
