, without calculating on a paper or something like that?

I know one for multiplication, but it does work only if you have: 12*19, or 25*24, or 58*52. It does work only if the number has the first number the same. I'm waiting for your opinions, and if you'd want me to show what I created without reading anything about this, I just wanted to know to do it much faster. I hope you understand what I mean. Thank you for your time.

I've been trying to find information regarding the history of the equality symbol (=). The most I've been able to find after several days of searching is
"The equal symbol (=) was first used by Robert Recorde (c. 1510-1558) in 1557 in The Whetstone of Witte. He wrote, "I will sette as I doe often in woorke use, a paire of parralles, or Gemowe lines of one lengthe, thus : ==, bicause noe 2, thynges, can be moare equalle." Recorde used an elongated form of the present symbol."
Does anyone know something more informative (for example, how people showed equality before "=" was the equality symbol) or know of a web page where I could find such information?
