# How to Assign Denavit-Hartenberg Frames to Robotic Arms
In this tutorial, we’ll learn the fundamentals of assigning Denavit-Hartenberg coordinate frames (i.e. x, y, and z axes) to different types of robotic arms.

The additive inverse, or opposite, of a number n is the number which, when added to n, yields zero. The additive inverse of n is denoted −n.
For example:
• The additive inverse of 7 is −7, because 7 + (−7) = 0;
• The additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0.
Thus by the last example, −(−0.3) = 0.3.
