A matrix is simply a set of numbers arranged in a rectangular table.

On the right is an example of a 2 x 4 matrix. It has 2 rows and 4 columns. We usually write matrices inside parentheses ( ) or brackets [ ].
We can add, subtract and multiply matrices together, under certain conditions.
We use matrices to solve simultaneous equations, that we met earlier. Matrices are used to solve problems in:
electronics
statics
robotics
linear programming
optimisation
intersections of planes
genetics
