According to medication standards, how is the numeral '4' represented?

The numeral '4' is represented as 'IV' in Roman numerals. In this system, numbers are formed using combinations of letters from the Latin alphabet. The letter 'I' represents 1, and 'V' represents 5. To indicate '4', the numeral is formed by placing 'I' before 'V', which signifies one less than five. This method of representation reflects the principles of Roman numeral notation.

Understanding this representation is important in various contexts, such as medication administration, where Roman numerals may be used in prescriptions or dosages to convey clear and standardized information.
