Math operations with arrays

I have almost no experience with Babylon, so please be merciful :slight_smile:
In the code I’m writing, I need to use dot products, cross product, matrix products and some inverted matrix because I trying to reproduce some complex movement and its equations have that kid of operations.
I’ve been reading babylon documentacion but I can only find API which I don’t really understand.
For Example when I search about dot product I find this website:

I don’t understand what all that information have to do with a dot product.
Somebody know where I can find some examples or tutorial that can help me.
Thank in advance

You will be luckier here: Vector3 | Babylon.js Documentation (


That document page is much more clear, thank you :slight_smile:
