Thanks Seven!
Numbers make my head hurt, though. (Ghosty did try to teach me, but I just got more and more green at the gills IRL and didn't retain most of it, sorry Ghosty, no reflection on his teaching ability.)
I dunno if I am stoopid or just have a sort of math phobia. :/
Is there any type of an auto align thingy?
I usually just align visually although so far my projects have been physically small, so that won't be as easy on a huge build, if I ever try one.

There is (are?) auto-alignment tools available. But aligning, for the most part, doesn't take a lot of math. Let's say you have two prims that make up a wall. You want to align them in height (Z axis) so the tops and bottoms are even, and you want to align them in X, their thickness axis, so you don't have a bump at the seam where they meet.
Open the edit window and pick the prim you want to use to match the other prim to. Note the value in the Z position window. Pick the other prim and enter the same value in ITS Z position window. Now repeat that process for the X position.
Aligning them so that they JUST touch, and don't have a gap or an overlap is trickier. You could do it with a little math, if you remember that the Y position of the second prim is going to be 1/2 the width of the first prim + 1/2 the width of the second prim away from the Y position of the first prim. (Position is measured at the center of any prim, unless you have specified differently).
But what I do here is usually visual alignment. Scoot the prim along the Y axis manually until it is pretty well in position. Then zoom in to the seam VERY closely and nudge the prim along the Y axis with the position box scrolling arrow. If the increment is too large, enter a smaller tweak manually in the Y position box. Look at the seam from at least two angles to see if it's lined up right.
Rotating a prim to make a perfect right angle is also easy...IF you start with a prim that is aligned with the world's coordinates (0,0,0 rotation, or some multiple of 90 degrees). Choose the first prim, SHIFT+drag to make a copy. Manually rotate the second prim to approximately the right position. Look at the rotation position boxes. Find whichever box has changed from 0 to some number that is close to a multiple of 90...87 degrees, let's say, or 265...and manually change that to 90, or 270...an exact multiple of 90 degrees.
