Math is a tool for a professional, a hobby for some others, and good for brain development in general.
Since it is not illegal to sing, to whistle, to dance, to play games, to talk, to kiss, to write, to eat or drink etc. in public, it is not illegal to do math, either.
It may look awkward or suspicious to stare at a computer for long hours, to sit on the same bench everyday, or taking pictures of a building for its architectural style, or texting in public etc. but they are all within our liberal rights.
Public safety is important, but, there is a price which is paid by everyone when fooled, no matter that person is an ignorant or a sophisticated one.
If you don't understand, don't panic. Just show some respect for other peoples' rights.
Something similar to this actually happened to me once in a trade show, where i was a vendor.
First some cops showed up, then i was questioned with some other officials. The reason was, because I was making little coils using copper wire for an experimental electric car. They told me to stop what i was doing, that, some other vendors scared of my playing with copper wire. I felt, like I was in a classroom. What a stupidity.
