Why is there no Divide By Zero Error here: http://sagecell.sagemath.org/?z=eJwljkELgkAUhO-C_2GiAtek1kuX2Eu4pBc3NjEqCqQ2E-QlpvX3cwuGd5jHzDdjZHGyw6BUZdgoFQXYx1JLa2WxRJTkSSSxPuAotYLUWumR64zRcDEJOecBtFhOA3QitHZpyLRFZ1BR03fDvdb9raISJLjrpKItqDReyNnq9Xh-vJTZkHkXdW9DjUcMvu__F2SIlNxhk-Tyt-UHH76usxUny_a9cMbnfLkgdiHcny1oICI9_8u37AuZcDtw&lang=sage
But there is a Divide By Zero Error here (as expected): http://sagecell.sagemath.org/?z=eJwlj0FLw0AQhe-B_IcnVcimQTeXXmQPtRnsXrJhG6q2WAh2GwtlGmKif9_dBoY5zJvvzZsZ6rXewNerMUWGNwK9V7SqsUSht7ogvHxgR9aArDX2Lo5m6KS6z6WUGaxaPGQYVB5HXcJChWma5HP5KBdPLA78_PN9_UuCJgLZOnZ9MzicuRsH378u4_HMLVjJOCpV33DrklyKiStvkPttLmOAgg3SNF2TJegahSGfW2_JP0FTPq_GUaX2t9XTtQf7Iyg_J79K_AMYbUA7&lang=sage Can soeone please explain this to me? This came up in class and I was looking for a "teachable moment" asking the students to fix the Divide By Zero Error like this: http://sagecell.sagemath.org/?z=eJwlj81qwzAQhO8Gv8OUtGA5ppUuuRQd2nhpdLGMYtI_WjCN4gbCxrh2-_qVYlj2sLPf7OwCzcZsEerJ2rLAM4Fealo3eEBpdqYkPL7ijZwFOWfdVZos0Et9raSUBZxe3RQYtUqTPmOh4zTP1FLeytUdi0--__k-_2VRE5HsPPuhHT2O3E9j6F-naX_kDqxlmlR6aLnzmSqUFDNZXTD_256miEUj5Hm-IUcwDUpLIbnZUXiD5oRBTZNav19WD-cBHM6g-pj9avEPiLZAmA==&lang=sage TIA, AJG -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
