I think "technical metal" is a better term. Try out Cynic - Focus, Extol - Undecieved, Spiral Architect - A Sceptics Universe, and Death - The Sound of Perseverance for some good stuff in that area..Meshuggah too, well if you can sacrifice a lot of melody....ok stuff but I'm not into them as much as the other bands.
Math(s) Metal is about the queerest name for a genre I think I have ever heard. There's nothing in that name to even make you want to listen to it. Somebody has to coin something better than that!
Math metal... lol... I thought some had found a way to use maths with something to do with metal... A practical use for maths? Nahhh.... Unless you are... A teacher! or an accountant, or work at a shopping till, oky, so perhaps there are a few uses for maths...
This is dumb. Mudvayne is just mallcore, they have like one or two tricky riffs/beats, nothing to be excited about. Meshuggah on the other hand does well at that, and Mastodon too I'm guessing although I haven't heard enough to know...
Acctually, Mudvayne are a great example. While their social status leaves a bit to desire, their guitar work and arrangement of music is pretty well done and always revolves around an equation or number.
