import proveit
# Prepare this notebook for defining the common expressions of a theory:
%common_expressions_notebook # Keep this at the top following 'import proveit'.

from proveit import Variable

%begin common

Defining common sub-expressions for theory 'proveit.abstract_algebra'
Subsequent end-of-cell assignments will define common sub-expressions
%end_common will finalize the definitions

Use these to denote addition and multiplication generically as variables

plus = Variable('boxplus', r'\boxplus')

plus:

times = Variable('boxtimes', r'\boxtimes')

times:

%end common

These common expressions may now be imported from the theory package: proveit.abstract_algebra
