Understanding Euclid: A Simplified Approach to Mathematical Thinking

I remember that my mathematical education started with numbers. First, my father, then later, my elementary teacher, taught me how to count as my elementary math education. However, 2400 years ago, everything was utterly different, and kids were taught geometry first. Before Jesus, geometry was more important than numbers. For instance, when the founder of the first institution of higher education in the Western world, <a href="https://en.wikipedia.org/wiki/Plato" rel="noopener ugc nofollow" target="_blank">Plato</a>, came back to Athens, he decided to found the <a href="https://en.wikipedia.org/wiki/Plato" rel="noopener ugc nofollow" target="_blank">“Academy,”</a> which would be <a href="https://en.wikipedia.org/wiki/Plato" rel="noopener ugc nofollow" target="_blank">the intellectual center of the world.</a> For that purpose, instead of taking a nonrefundable application fee, he engraved “ΑΓΕΩΜΕΤΡΗΤΟΣ ΜΗΔΕΙΣ ΕΙΣΙΤΩ” (Translated from Greek as “Let no man ignorant of geometry enter.”) at the door of his academy to eliminate those who were opposed. <a href="https://ali.medium.com/understanding-euclid-a-simplified-approach-to-mathematical-thinking-5779948da80e">Website</a>
