quick "at?"

I have come across a sentence,"He is quick at solving mathematical problems". My dilemma is that I checked up the dictionary and I didn't find any sentence in which the preposition "at" is suffixed with "quick". The only quoted suffixed preposition is "to".Please explain whether "quick at" is correct or not.

    'Quick at' + gerund-participial phrase, 'quick to' + infinitival phrase (where the 'to' is not the preposition but the subordinator marking an infinitival): He is quick at solving the problem; he was quick to solve the problem.
