Yet another question for our former British overlords

It could just be because it's a newspaper headline and 'math' scans better on the page.

We would never say 'math teacher' for instance. So, it's not normal usage.

It could also be an Americanism :p

I noticed the other night on Newsnight, John Snow was interviewing someone and referred to a solution (to what i dont recall) as 'merely a bandaid'. We don't have 'bandaids', we have 'plasters'. But the term is starting to be used more often.

British English is changing and incorporating American terminology. It's not a new phenomenon, but it has sped up quite a bit as communications have become more fluid and global.
