I recently purchased Mathmatica 3.0 Student version and installed it on my home computer. Since that time I have purchased a laptop. I would like to have mathmatica on my laptop more than I would on my home system and I am unsure of the legalities of this. My question is, can I install Mathmatica on my laptop or do I need to delete it off of my home computer first? Please let me know what I should do. Thanks.
