Science is art, art is science.

This page contains math emojis: add, subtract, multiply, divide. Actually most of the time they are not used according to their initial purpose. Formulas and equations? Off the table. Add substances, subtract materials, divide parts, multiply processes — that's what we want!

In any case, the most peculiar use falls on the shoulders of the permanent paper emoji, because it's almost never used as intended. 「That makes sense, because I don't see paper, I see a sign of eternity!」 — you'll say. And you'll be right.
