Linear algebra

From Wikipedia, a free encyclopedia written in simple English for easy reading.

Linear algebra describes ways to solve systems of equations.

For example consider the following equations:

\begin{matrix}  x &+& y &=& 0 \\  x &-& 2y &=& 3 \end{matrix}

These two equations form a system of equations.

Linear algebra uses a system of notation for describing system behavior, called a matrix.

For the previous example, the coefficients of the equations can be stored in a coefficient matrix.
