- computer algebra system (CAS) can be used as an algebraic calculator
- one can program in a CAS using a high level language
- one can get VERY LARGE algebraic expressions quite easily
(see
expression swell)
- it is hard to guess the memory and CPU time requirements for a given
calculation
- often calculations need to be done only once--once a result is known,
it does not need to be calculated again
- efficiency questions (algorithmic)
- questions of representation which can influence the efficiency as well
- experience is very important
