It means "intersection", used in set theory.
A ∩ B means all the elements that are contained in both sets.

The symbol that looks like a U is union. A U B means everything in A or B.
The symbol that you gave, which I can't make means intersection. This is everything in both A and B. It's like the intersection of two streets. That part of the road is in both streets.

"Intersection" is the correct answer. Union is denoted by a "U"
Come on people since when was "∩" EVER used as a variable??? Give me a break. As for it being a parabola...well the actual character might be, but that was not the question; he asked what the symbol "MEANT"

A n B is read as "The intersection of set A and set B"
It is the set containing items that are in BOTH set A AND set B.

Intersection. It's like "and" but for sets. The intersection of one set and another is the set of elements that are contained in both sets.

"n" usually serves as a variable in some math problem. Unless there was a specific meaning given to you in a specific problem, it really has no meaning other than that it's a number or value that you don't know.

The Varible. Usally subtract them from both sides.

Intersection. It is an operator on sets. For example, {women} ∩ {doctors} = {female doctors}.

It is intersection. That is the things that are common to two or more sets.

its an upside down parabola and the right side up one is what you see if you graph a rule with square in it or you can get a sideways one if the rule has square root in it
