What is the difference between compulsory mathematics in high school and basic mathematics module in secondary vocational school (both are PEP editions)?
The questions you ask must be on the topic so that everyone can help you. Who has a pile of reference books with him for future reference?

When asking questions, please put yourself in the position of helper, otherwise people will despise you for not knowing how to ask questions.
