| Given Euclidean geometry and Cartesian co-ordiantes, how do *YOU*
| calculate the following.


Co-ordiantes? What are they? Oh... you mean coordinates.
You need coordination between fidgets and digits.


| We have 2 points in space, A and B.
| Point A has co-ordinates x_A, y_A, z_A.
| Point B has co-ordinates x_B, y_B, z_B.
|
| Let x_A = 89, y_A = 45 and z_A = 56.
| Let x_B = 94, y_B = 35 and z_B = 74.
|
| What is the distance between point A and point B?

(5,-10,18)

| What is the distance between point B and point A?

(-5,10,-18)

It is just simple vector addition, really. Distances
are vectors.
