Hello

If a vector is multiplied by a constant (number), then all components of the vector are multiplied by this constant:

3 * (a_x | a_y | a_z) = (3 a_x | 3 a_y | 3 a_z)

At a) you multiply the direction vector
with a constant, you divide him, for example, by 2.

At b), you simply subtract a direction vector
from the support vector.

There, a direction vector was added to the support vector. That’s it.
Only a multiple of the direction vector to/from the support vector must be
are added/subtracted.

Then you divided by six, that goes too.
Which number it is doesn’t matter.
