Imagine that you want to write something about colors and you know that red or blue would work in that context. How do you write that? I've seen these styles:
- Red or blue
- Red, or blue
Why is this sign used as a substitute for 'or'? I mean, in computer engineering, '|' represents 'or' and in mathematics, 'V' represents 'or'. Is there any reason why this symbol is chosen?
PS: The same case is true about '&' sign (ampersand).
