You're not learning how to perform calculations in most calculus courses. Perhaps not even most algebra courses.
A given expression can be simplified/factored in multiple ways. That TI-89 is going to do it only one way. When working with a typical physics/engineering problem, the way you decide to arrange the terms can help tremendously in understanding the physics of the situation.
I hear this take only from people who've not gone ahead and done advanced (graduate) level work.
