RE: dot product vs star symbol ?
yes, ok...
but, rigorously speaking, "dot" and "times" are used also for "dot product" and "vectorial product" (this one also with "wedge" \( \wedge \), sometimes)... gradient \( \nabla \vec{v} \) divergence \( \nabla\cdot \vec{v} \) curl \( \nabla\times \vec{v} \) dot product \( \vec{u}\cdot\vec{v} \) vectorial product \( \vec{u}\times\vec{v} \) (or \( \vec{u}\wedge\vec{v} \)) That said, I think that something like "times" (\(\times\)) (or also "dot" (\(\cdot\))) is better than the star *, for multiplication ∫aL√0mic (IT9CLU) :: HP Prime 50g 41CX 71b 42s 39s 35s 12C 15C  DM42, DM41X  WP34s Prime Soft.
