To add the vectors (x₁,y₁) and (x₂,y₂), we add the corresponding components from each vector: (x₁+x₂,y₁+y₂). Here's a concrete example: the sum of (2,4) and (1,5) is (2+1,4+5), which is (3,9). There's also a nice graphical way to add vectors, and the two ways will always result in the same vector.​​

Discrimination can be defined in two ways: individual and institutional. Individual discrimination refers to the prejudiced behavior of one person, while institutional discrimination refers to the way an organization's rules or policies disadvantage certain groups. Although they are distinct, these two forms of discrimination can be interconnected. Individual discrimination can be reinforced by institutional policies, and vice versa, which leads to a larger, systemic issue. (. Created by James Howick.
