+<!-- Feel free to remove sections marked optional if they are not relevant. The other sections, please fill out. See also https://github.com/Mathics3/mathics-core/blob/master/REPORTING-BUGS.md -->
+
+## Description
+
+<!-- Please add a clear and concise description of the bug. Try to reduce the bug to the minimum   expression that exhibits the bug.
+     For example, if an expression occurs with several terms, can these be removed and the bug still appear? If so, we would like the reduced, simpler expression.
+
+      If the expression can be written in SymPy, does SymPy also exhibit the problem?
+-->
+
+## How to Reproduce
+
+<!--
+Steps to reproduce the behavior.
+
+For Django:
+1. Go to ...
+2. Enter ....
+2. Click on ....
+3. Scroll down to '....'
+4. See error
+
+For a command-line environment:
+
+$mathics -c 'E ^ (Pi I)'  # adjust expression E ^ (Pi I) for the specific bug
+
+-->
+
+## Output Given
+
+<!--
+Please include not just the error message but all output leading to the message, which includes echoing input and messages up to the error.
+For a command-line environment, include the command invocation and all the output produced.
+
+If this is too long, then try narrowing the problem to something short.
+-->
+
+
+## Expected behavior
+
+<!-- Add a clear and concise description of what you expected to happen. -->
+
+## Your Environment
+
+<!--
+
+Sometimes problems are specific to a particular environment or
+software release. If you have access to several environments, it is helpful to check whether this fails on more than one environment.  Please
+indicate that when available.
+
+If you are using a recently released Python package that Mathics3
+uses, it is possible we haven't tested this, and the new package is not
+compatible. Try on an older software release, and if that is still the problem, let us
+know about the breakage in the version.
+
+In either case, please include the output from:
+
+  mathics --version
+
+This information is also posted when you enter either the `mathics` or `mathicsscript` commands.
+
+If you are running from a browser Django, please note the browser type, e.g., Firefox, Chrome, Safari.
+
+Inside Django, http://localhost/about provides information, which you can cut and paste here.
+ -->
+
+## Workarounds
+
+<!-- If there is a workaround for the problem, describe that here. -->
+
+## Priority
+
+<!-- If this is blocking some important activity, let us know what activity it blocks. -->
+
+## Additional context
+
+<!--
+This is optional. Please add any other context about the problem here or special environment setup.
