How does this translate into english?
Let p, q, and r be the following statements:
p: Roses are red
q: The sky is blue
r: The grass is green
( ~ r ^ ~ q) --> ~ p

^ means and.
~ means not, i.e. if r is "The grass is green" then ~r is its negation, "The grass is not green".
a -> b means "if a, then b" or "a implies b" or, somewhat confusingly "b, if a".
So it's:
If the grass is not green and the sky is not blue, then roses are not red.
