You have always been able to add and subtract in any coordinate box and in the Tracker, but division and multiplication is not possible AFAICT.
Addition and subtraction uses HP-style calculator "reverse polish" - that is, the + or - is entered after the number.
With the Tracker, you need to enter an extra letter or two.
For example, suppose you want a wall that is 2000 + 1500 mm long.
You would start the wall and then enter R2000R1500+
That's a bit lame, since you can do it in your head, but easy to try.
More typical would be that you want a new wall to extend past a known point by 1000 mm (e.g.). Start drawing the wall, press the shift key until you align the wall length with the known point by snapping the mouse cursor to the point and while still at that position, press "R" and then enter 1000+ in the Tracker (if visible - or the coordinate box if no Tracker but Coord box on). The math is completed with the "+". Pressing the Enter/Return key completes the wall.

PS This reverse polish addition/subtraction works in most places. For example, with the Info palette open and the Wall Tool selected, if you enter (using upper case just to make it visible here - either is OK):
T50+
then you add 50 mm to the top of the wall, making it 50 mm higher.
B50-
would extend the base of the wall 50 mm lower
Etc.
(US Imperial unit users have to use an extra "-" for subtraction to clarify that it is subtraction and not a foot-inch separator. So, to subtract a foot from the top of a wall, you would enter:
T1--
but to subtract 1'-1" from the top you would enter
T1-1-
where the first dash is the foot/inch separator and the last one is the subtract operator.)
