About this symbol
The equals sign came first, invented by the Welsh mathematician Robert Recorde in The Whetstone of Witte in 1557. He chose two parallel lines because, he wrote, no two things can be more equal.
Crossing it out to mean “not equal” is usually traced to Leonhard Euler, who at least used the sign, even if he did not invent it.
