Hey all, if there is a high up math whiz maybe you can help me out here on this one

I'm kind of not a HUGE math fan but am wondering on a couple points...(hope this isn't like a RANDOM question)

My question is actually fairly simple: can equations and the like be configured (set) so that they might reflect something from higher than 3rd dimension? i.e 4th 5th and higher?

not sure if this is accurate or not, however, is there not more than 3 known dimensions in reality? i'm not asking this in physics forum because i'm asking about the math side of this!

for example, could someone write an equation that demonstrates what an object would look like in the 4th dimension, or similar? Certainly I'd like someone to back up that if it's indeed a fact.

unfortunately, I went all the way to Algebra only as HS grad! no calc, trig nothing.

if someone could point this out for me I'll give you a slap on the back and possibly...say...$300 monopoly dollars. :P

and I'm asking out of curiosity not looking for sadisticness here.
