Puzzles me too. And even further : IIRC, you don't need cross-product for electrical engineering, and IIRC it (thankfully) isn't (generally?) taught in high school. Furthermore, later, in college, it would seem that electromagnetics get easier when taught through bivectors rather than cross products (and you avoid the traps with pseudo-vectors and, later, gimbal lock with Euler angles ?). Maxwell's multiple equations seem to condensate to a single one under GA ! (What if we teach GA it will open the possibility of teaching EM in high school ?)
