A discussion on LinkedIn group «Math, Math Education, Math Culture» includes a simple question:
« What is the most important math sign (symbol) ? »
The question is vague, so everybody can differently interpret it.
There were more than 30 comments.
The proposals include:
0 1 + = ! … < * pi f(x) “all of them”
The several people mentioned “equals” sign (=).
Robert Recorde (1512–1558), a Welsh physician and mathematician introduced the modern “equals” sign (=) in 1557.
We can simplify something (2 + 3 = 5) or complicate the things (5 = 4 + 1) by using the sign. It is also my favorite.
