What numeric value does the letter "X" represent in medical terms?

In medical terminology, the letter "X" commonly represents the numeric value ten. This is rooted in Roman numeral notation, where "X" is the symbol for ten. Understanding Roman numerals is particularly relevant in various aspects of medicine, such as denoting the number of units (e.g., doses of medication) or when describing anatomy, such as labeling structures or quantities in clinical documentation. Recognizing the value of "X" as ten can be helpful for medication aides when interpreting prescriptions or medical records that may utilize these numerals.
