Description: The four element number is a simple super complex number. The complex is composed of real and imaginary unit of I, where i^2 = -1. Similarly, the number of four yuan is composed of real and three imaginary unit of I, J, K, and they have the following relationship: i^2 = j^2 = k^2 = -1, i^0 = j^0 = k^0 = 1, four yuan each number is a linear combination of 1, I, J and K, i.e. the number is four yuan in general can be expressed as a + bk+ CJ + Di, B, C, a, D is a real number.
For I, J, K geometric meaning itself can be understood as a rotation, which represents the X I rotation axis and Y axis plane intersecting the positive X axis to the positive Y axis rotation, J rotation represents the Z axis and X axis plane intersecting the positive Z axis to the positive X axis rotation, K rotation Y axis intersects the Z axis in the plane of the positive Y axis to the positive Z axis rotation, -i, -j, I, J and -k respectively represent the K rotation and reverse rotation
