I can show you how to do it on a TI- *n* spire *cx* :

If we use [How do you find the cross product ...] (https://socratic.org/questions/how-do-you-find-the-cross-product-and-verify-that-the-resulting-vectors-are-perp-2) as an example.

This shows that:

#<<3,2,0>> xx <<1,4,0>> = <<0,0,10>> #

On the TI- *n* spire *cx* we calculate the cross product using the
