5.5     Math
  Basic maths operations on any combination of any
objects. You can add a slider to a matrix, for example,
then divide by an image. Hopefully most of these are
obvious.

Arithmetic / Absolute Value Vector 
- The   absolute   value
    item normally calculates mod of each band of an
    image separately. By contrast, Absolute Value Vector
    treats  each  pixel  as  a  vector  and  calculates  the
    modulus of that.

List 
- These aren’t really maths operations, but they’re in
    here too.
