Question

what are the set notation symbols and their descriptions?

Answer 1

I still remember from 7th grade algebra that \[\cup\] means union

Answer 2

http://www.me.berkeley.edu/ME280B/notation.pdf

here's a list of set notation symbols, but you will probably only need to know the ones at the very bottom of the pdf (the others are simply for physics expressions)

Answer 3

ignore the vectors and tensors :-P

Answer 4

U means union, and attaches the two sets together. The n is an intersection and means all elements that are in both sets.

\[\subseteq\] means proper subset of and can be interpreted as subset or equal to.
\[\subset\] means subset.

\[\supseteq\] means proper superset of and can be interpreted as superset or equal to.
\[\supset\] means superset.

\[\in\] means element of a set.

\[\notin\] means not an element of a set.

\[\prod_{i=0}^{n}\] means the iterated product, like a summation but multiplying each item by the one before it.


The same type of iteration exists for unions and intersections.

Hope this helps. If it does, please choose good answer.
