Set of 5 Mathematic Computer Software Learning CDs

Set of 5 Mathematic Computer Software Learning CDs. All appear to be in very good used condition and played without issue the last time they were played 10+ years ago. The trigonometry CD is still sealed in original plastic. Computer software CDs have not been recently tested. Would be good for someone who is familiar with computer software and owns a CD ROM drive in their computer. Check listing for computer compatibility. New to Poshmark?
