Hi vpl There is a ticket about adding maths expressions to the core filter syntax:
https://github.com/Jermolene/TiddlyWiki5/issues/254 There's no specific proposal for the syntax at the moment. My own preference is that we should re-use standard mathematical expression syntax as far as possible, and not invent a different syntax for math operations. Best wishes Jeremy.
