¡Los números!

Imagine how life would be had numbers not been invented. Most people would claim it would be an incalculable mess… literally! For a start, we could not count, nor could we order book pages or identify people and objects based on their identity documents and barcodes respectively. In a numberless world, we would not be able to measure anything, nor could we organize meetings as we would not be able to read the time. Similarly, we would not know which bus to take to go places, we could not call anyone nor could we learn things’ prices, let alone being able to use money. A dreadful scenario indeed! We are then unquestionably way better off with numbers as an essentially omnipresent component of our lives.

Here are los números desde (from) el 1 hasta (to) el 20:
