It is. Try searching for 16*9 for the good reason it shows both the calculator, and then links to 16:9 and 16x9 aspect ratio content.

It's reasonable to think that the calculator already answered the question, and I'm not looking for pages on the simple multiplication once I've already seen the answer.

Imagine the uproar if those results didn't come up because a bunch of children's math quizzes were found instead.

So what you're saying is that google sucks at context clues

It clearly understands enough to trigger displaying the calculator.

What we'll discover is there is a team dedicated to determining when to display the calculator. Then there will be another team entirely that picks how to interpret the query for website results. The two teams will never have met, spoken, exchanged information between the two. The team searching websites will mysteriously have never thought that someone might search a webpage for a math equation.
