A cube is an integer that you can get by multiplying a number by itself 3 times.
e.g.: 1 * 1 * 1 = 1; therefore 1 is a cube.
e.g.: 3 * 3 * 3 = 27; therefore 27 is a cube.
Two cubes added together can be factorized into a simpler form.
i.e.:
[tex]x {3} + y {3} = 0[/tex]
can be simplified into:
[tex](x + y)(x^{2} - xy + y^{2} )[/tex]
