Didn't say from that point. The OP is talking about Maths here and is also about Mathematical symbols. 



How is it related? Does one symbol get used more in applied rather than in academic mathematics?

One good example is the symbol of equality, “=.” This relation was mostly expressed with words in the beginning. Later [René Descartes in France started using the rotated Taurus symbol, “∝,” while [Gottfried Wilhelm] Leibniz in Germany used a wedgelike shape. And [before Descartes and Leibniz] Robert Recorde in [the U.K.] invented the equality sign we use today, though in an elongated form.
