Il mio
'Il' is the definite article ('the') and 'mio' is the possessive adjective ('my'). In Italian, possessive adjectives usually require a definite article before them, unlike in English, except with singular, unmodified family members.
prof
This is a common and widely accepted abbreviation for 'professore' (male teacher/professor) or 'professoressa' (female teacher/professor). It is used in both informal and semi-formal contexts in Italian schools and universities.
di
The preposition 'di' means 'of' or 'from'. Here, it indicates the subject taught, forming the phrase 'teacher of mathematics'.
è
This is the third-person singular form of the verb 'essere' (to be), meaning 'is'. It is used to state identity, profession, or characteristics.
il signor Smith
'Il' is the definite article, and 'signor' is the title 'Mr.'. In Italian, when referring to 'Signor', 'Signora', or 'Signorina' followed by a surname, a definite article (il/la) is generally required, unless you are addressing the person directly.

Cultural Tip
'Prof' is a very common and accepted abbreviation for 'professore' or 'professoressa' in Italian schools, from middle school through university. It's not considered overly informal and is used by students and even other faculty members. While you would address a teacher directly as 'Professore/Professoressa' or 'Signor/Signora [Surname]', referring to them as 'il prof' is perfectly normal in conversation. The Italian education system typically has specialized teachers for each subject from a relatively young age.
