sentence : Every cube is larger than something else.
My Working:
P(x) = x is larger than something else
∀xP(x)
But the answer is something completely different. ∀x (A(x) → B(x)) : the answer
How does the answer equal to this? And is there a trick to translating sentences into quantifiers and predicates that I don't know about Because this is just one of the questions I got wrong and for some reason I can't get any of these questions right.
Well in your sentence you're missing the fact that x is a cube
So to stick with the solution notation i would go
$A(x)$="$x$ is a cube"
$B(x)$="$x>$something else"
Then the solution is indeed correct
