Hello everyone, it's been a while since I've gone on these forums. Anyway, in my first lecture today I received a syllabus and on it was this equation. I have not done any calculus in two years so forgive me if this math is extremely simple.

I realise that the first part shows that the midterm is worth 40% and the final 60%, but the second half confuses me.

Any explanation would be greatly appreciated as this is quite important for me to know.

Thank you
