Theorem add_cancel_general of type Forall ¶

from the theory of proveit.numbers.addition.subtraction ¶

In [1]:

# Automation is not needed when only building an expression:
proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

# import the special expression

Passed sanity check: add_cancel_general matches stored_expr
