Virtually any mathematical principle can be applied tondimensions. Generally we think of the dimensions as:

1D: Number line

2D: X-Y plots

3D: X-Y-Z planes/space

All of these can be drawn and imagined concretely. Math in the 4th, 5th, 100th dimension etc. is possible but there is no way to draw it. It can't be put on paper or even in a computer.
