However, if a sentence begins with a numeral, always spell it out., e.g., "Seven people attended the lecture." * A few more exceptions to spelling out a number past "nine" is that temperatures and longitude/latitude are always spelled out. You can write 5:34 a.m., but when it's an even hour you write it 5 a.m. Anti Meridian (means before noon, whereas p.m. is post meridian [after noon]). Both are Latin and should be capitalized but since it's not dominant to the sentence it is not capitalized as it is too distracting to the numbers indicating the time.

I believe that this question is missing some information and seems to refer to 'In Writing. Which is my question; In writing should one use digits to represent numbers? And if so would they still be considered adjectives? Because they are describing the noun number or whichever other noun they are describing.
