May 19 at 16:00 comment added James @Will, you would say "maths is difficult", in the same way one would say "The Beatles is a band", or "physics is easy".
Jun 19, 2015 at 15:19 comment added Will Absolutely. By calling it "the original set" and "S" it really helps to remain unambiguous. Talking about multiple abstract structures can get very confusing.
Jun 19, 2015 at 15:02 comment added Marc Andreson @Will ok. and referring to S can I use something like "...with elements from the original set S" ? so that make it explicit "the original set"
Jun 19, 2015 at 14:59 comment added Will Here's my best shot at what I think you're trying to say (the math may be beyond me :D ) Create a set S, with elements 1, 2, 3, 4. Create a new set with the same elements, T. Remove 4 from T. So when you duplicate a set, it become a different set, with a different name, while the original set is unchanged. Is this what you mean?
Jun 19, 2015 at 14:55 comment added WhatRoughBeast When referring to individual letters, the choice of a or an is determined by pronunciation. The vowels (but not 'y') and 'f', 'h' ,'m' ,'n' ,'r', 's' and 'w' are preceded by "an", since they are pronounced as if they start with a vowel. "F", for instance, is pronounced as if it were spelled "eff".
Jun 19, 2015 at 14:49 comment added Marc Andreson What if I want to add also an adjective, say "Create another set S. Remove element 4 from the new set S" ?
