do number four in all roman clocks still always be written as IIII instead of IV

No, the number four in Roman numerals is typically written as "IV" in all contexts, including clocks. The use of "IIII" to represent four is an exception and not a standard practice in clock faces.

Here are some key points to remember:

1. Standard Roman Numerals: The correct representation of four is "IV" (5 - 1 = 4).

2. Historical Exceptions: In some historical sundials or traditional clocks, you might find the number four represented as "IIII" for aesthetic reasons, such as maintaining symmetry in the clock face.

3. Modern Clocks: Most modern clocks follow the standard Roman numeral system and use "IV" for the number four.

4. General Usage: In mathematics, literature, and everyday applications, "IV" is the universally accepted form for the number four in Roman numerals.

In summary, while there are a few historical exceptions, the number four is generally and correctly written as "IV" in Roman numerals, including clocks. Using "IIII" is not a standard practice and should be considered an exception rather than the norm.
