With Evan Balster's formula plugin the formula looks like this: (= (636-2*(22)-2*(32))/5 =)

resulting in: 105.60

not that complicated.


Your 2nd question: "/which math plugins for TiddlyWiki can do this simply?"
/*simply? none/. Math is painful.
*/math plugin of choice/: Evan's formula plugin. /Its the Tyrannosaurus of all plugins

I get

separation distance = (636-2(22)-2(32))/5 = 105.6 cm

So first center starts at 22+32 = 54 cm and each center is separated by 105.6 cm

#1 54
#2 159.6
....

check the math

    I have a problem. I'm crap at math.

    The problem is to calculate the "hanging points" for 6 paintings.

    These are the inputs ....

    - the wall is 636 centimeters long;

    - the offset of the edge of first and last frames is 22 cm from
    the start of the wall (left) and end of the wall (right).

    - the frames of each of the six paintings is 64 cm wide.

    What is the calculation that will give me the list of "mid-points"
    (the painting's lateral centres) such that I can equally space the
    paintings? (Practically I need the measure of the centre-to-centre
    distance of the paintings within the specified length, taking into
    account the offsets.)

    That is the first part, to get the math.
