Mathematical objects '''intersect''' when they have something in common. For example, the sets {1,2,3,4} and {2,4,6} intersect as {2,4}.
Mathematical objects '''intersect''' when they have something in common. For example, the sets {1,2,3,4} and {2,4,6} intersect as {2,4}.
For two sets A and B, their '''intersection''' is written as A∩B and is formally defined as A∩B = {x|xϵA AND xϵB}.
