I'm glad I don't really have any maths, except for linear algebra and logics.

P(x,y) means x is the owner of y.
D(x) means x is Dutch
C(x) means x is a car
B(x) means x is a bike

∀k(D(k)) means every k is Dutch
∃x(P(x,n)) means there is a x who owns n
→ means "if"
P(x,y) → D(x) means if x is the owner of y, x must be Dutch.
∨ means "or"
& means "and"

With all that info, what does this mean:
∀x(N(x)→[9y(F(y)^H(x, y))^
∃uvw((A(u)^ A(v)^ A(w) ^
H(x,u)^H(x,v)^H(x,w))
→[u = v u = w v = w])])

Anyway, what it meant was every Dutch person owns at least one bike and no more than two cars.
 
216574. What's the subject of that exam Katalyst?
 
Waves and Continuum Mechanics.
Not easy, loads of stuff to revise and not a lot of time since I've had two other exams before this one.
