(CAS) Symbolic vs Numeric Solver (Non CAS)

[tim_crouse]

Thanks for the response.

Would you happen to be able to point me to a good example of when to use CAS.

My understanding of your answer is that CAS is helpful to work through the steps of an equation but at the last step you may have to switch to the non-cas solver to get a numeric solution to the entire equation set , Or maybe this is just one use case.

Not really a calculator question but when would a solution to an equation be an expression ( say in Algebra 1 or Algebra 2)?

Thanks For Your Help
