OK writers, here is a question for you. Do you think it is correct to write "20+" as twenty some? Because, I don't know if you notice, and this might be a British variation, but the "+" (plus) symbol is also known as a sum symbol. Although most people reading a line of text would probably verbalize the occurance of such an entry as "twenty plus", I'm simply clarifying whether the probable misinterpretation sum with some might not be a result of a TV series called 30 something. Remember that?
