boxless, stay away from math. it ain't your subject. yes, the numbers are
multiplied

(as I showed you how yesterday)

but NOT as you did it

(which is different from the way I showed you yesterday)

and gives you bogus results

(which I showed you how to avoid yesterday)

marts, stay away from math. things like two lines normally define a plane
and
planer space expands multiplicatively are beyond you.


Huh, learn to proof read. Also see if you can find out the difference between
mathematics, arithmetic,
trigonometry and geometry.

So if you have a compass with 40 degrees of error, (large but not unheard
of), and you
"align" your RDF (which being assembled by you from a kit from Heathkit) has
an error of
40 degrees, you could be of by 400 degrees? Astounding Jax, simply
astounding.

oh? errors don't multiply?


In this case that is correct.
