How does a 4 look like?

A "4" typically appears as a numeral with a straight vertical line on the left side, a horizontal line at the top, and a diagonal line connecting the two to form a shape resembling a triangle. In some fonts, it may have a small horizontal line in the middle. Its design can vary slightly depending on the typeface, but it generally maintains this structure. In a digital context, it is often represented in a clear, bold format for easy readability.
