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:

$\left\langle3 , 2 , 0\right\rangle \times \left\langle1 , 4 , 0\right\rangle = \left\langle0 , 0 , 10\right\rangle$

On the TI- n spire cx we calculate the cross product using the $\text{crossP()}$ function:
