How to clear this variable

Question

I can not clear this variable. How to clear?

See https://mathematica.stackexchange.com/questions/373/clear-complains-that-a-subscripted-variable-is-not-a-symbol-or-a-string or https://mathematica.stackexchange.com/questions/128498/how-to-clear-the-downvalues-of-a-subscripted-variable, perhaps. — Michael E2, Jul 18 '21 at 04:40
People here generally like users to post code as Mathematica code instead of just images or TeX, so they can copy-paste it. It makes it convenient for them and more likely you will get someone to help you. You may find the meta Q&A, How to copy code from Mathematica so it looks good on this site, helpful — Michael E2, Jul 18 '21 at 04:41
For yet one more complication of this phenomenon in the setting of assigning values to spans of subscripted variables, see https://mathematica.stackexchange.com/questions/249706/assignment-with-span-to-indexed-variable — Nicholas G, Jul 18 '21 at 06:48

To clear Mathematica variables that are not symbols you set them equal to .

Subscript[\[Sigma], \[Epsilon]] =.

This will clear it.

Don't use subscripts. Mathematica does not not handle them very well and in general they cause nothing but problems.
