Who would imagine that the number 1 – this little vertical line so familiar – went through millennia to reach us? His story astonished and it seems that he remains indispensable at every time.
At the origin of the number 1: a universal symbol
The number 1 appears more than 5000 years, in Sumerians, in the form of a simple stick engraved on clay tablets. This discovery opens up the possibility of the very first counting "one by one", a principle that will become the foundation of numeration throughout the world.
Over time, every great civilization – from the Greeks to ancient India, through Egypt – invents its own sign to represent unity. We must wait until the fifth century before the « 1 » In its present form, Arab numerals are becoming a universal tool.
The same is observed regularly: the 1 remains symbol of the beginning in almost all cultures. It marks the transition from nothing (zero) to the appearance of the very first element. Some historians even evoke a singular charm attached to this idea of starting, especially in family transmission stories.
The evolution of 1 in the numeration systems
First used to enumerate concrete objects, the number 1 requires as the basis for all other values – without 1, impossible to write 10 or 100, or even to grasp the principle of addition.
An interesting anecdote: in ancient Rome, the letter "I" represented the 1, both on sundials and in official documents. Today, this "I" remains visible on clocks or in the numbering of films and books (we think spontaneously of Star Wars I).
Last point to note: over the centuries, the number 1 always plays the role of ambassador of the beginning. This phenomenon is still found in certain rituals, such as the one that starts counting with a "one step".
Mathematical and computer applications
Unable to learn to count without going through the number 1: for many students in kindergarten or CP, he is like the very first "friend", before discovering the other values. But it also reserves very practical surprises for adults.
Number 1, basis of arithmetic and science
In mathematics, the number 1 represents the additive unit. In other words, it's the only number that, combined with itself, is used to build all the others: 1+1=2, 2+1=3... In the family, this progressive learning is relatively often observed: first give the child an object, then two, then three.
In geometry, a point is the symbol of a "only location". For fractions, the number 1 serves as an absolute reference: 1/1 is 1, which perfectly illustrates equality.
A trainer suggested that the number 1 is the only square number that can be considered at once even and odd – this point always makes enthusiasts of mathematical records smile!
The importance of 1 in computing and everyday life
In the computer language, the 1 remains essential: it is one of the two basic "bits", alongside zero (0 and 1). That's also why computers, phones and video games work with suites of 0 and 1.
One might wonder where the number 1 is in the current life:
- ✅ You see it on computer keyboards: the key "1" is the first left.

The number 1 also evokes the notion of "first": first of the class, first star of the evening... It is an invitation to undertake, to initiate, to become a pioneer in his life. Moreover, many religions speak of a unique God, the source of all creation – an analogy that goes through centuries.
