When data is written with quotation marks, it is treated as text—a string. The characters inside the quotes are a sequence of symbols, not a numeric value. So "99" is a string containing the digits 9 and 9 as characters. It isn’t a numeric type unless you convert it. If you wanted arithmetic, you’d convert it to a number (e.g., 99 as an integer). Without quotes, 99 would be an integer, and 99.0 would be a float. Booleans are true/false and not digits. So the data type of "99" is a string.
