It's actually wrong to send "brother" or something. Although it comes from Latin, symbols are used here. It has completely lost the value of language, just an operation symbol, so if you want to read it, you have to read the operation name. "log2 32" should be read as "logarithm of 32"; "lg 100" should be read as "common logarithm of 100" or "logarithm of 100". The symbol "log" has the same status as+-×××. You cannot pronounce "+"and "-"as "addition" or "subtraction". Similarly, this symbol cannot be pronounced as "brother". So is the triangle ratio symbol.
