mental age involves calculating the chronological age at which a person functions

Explanation:

Mental age is expressed as the average age that a person reaches the same abilities. You can be 50 years old but at a mental age of 10. You can also be a 10-year old that operates at the mental age of a 15-year-old. That means that at age 10 you perform intellectually the same as an average 15-year-old.
