01 — Origin
Where the Division symbol comes from
The obelus was introduced as a division sign by Johann Rahn in 1659. Before that the same mark was an editorial symbol used since antiquity to flag a passage of doubtful authenticity — which turned out to be prophetic, because mathematicians now avoid it as ambiguous.
School arithmetic and calculator keys. Professional mathematics uses a fraction bar or a slash instead, because expressions like 6 ÷ 2(1+2) have no agreed reading — the reason that particular sum goes viral every couple of years.
