Language equations

We have some puzzles I would like help with for example,10 L.I. Does anyone know what this phrase would be?

Hi confused, there's a site that specialises in this stuff. I've stumbled across it before. Especially the ones that provide numbers & letters like your example - kind of word algebra. I can't remember what it (or they) is/are called - so I'll go looking, but meanwhile, maybe some of the other guys here know???

10 Little Indians.

Something similar is called a language equation. 10 L. I. isn't quite that: no equals sign.
