Linear algebra

Branch of mathematicsLinear algebra is the branch of mathematics concerning linear equations such as a1x1+⋯+anxn=b,{\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}=b,}linear maps such as the following: (x1,…,xn)↦a1x1+⋯+anxn,{\displaystyle (x_{1},\ldots ,x_{n})\mapsto a_{1}x_{1}+\cdots +a_{n}x_{n},}and their representations in vector spaces and through matrices.
