Cultural Tip
The use of 'profe' and 'mates' is very common in Spain and many Latin American countries, especially among students and in informal conversations. While 'profesor/a' and 'matemáticas' are correct, using the shortened versions makes your Spanish sound more natural and fluent in casual contexts. 'Sr.' is the abbreviation for 'Señor' (Mr.), and it's customary to use it with the definite article 'el' when referring to someone by their title and last name.
