Expression of type ExprTuple

from the theory of proveit.numbers.addition

# build up the expression from sub-expressions

# check that the built expression is the same as the stored expression
assert expr == stored_expr

Passed sanity check: expr matches stored_expr

# Show the LaTeX representation of the expression for convenience if you need it.
print(stored_expr.latex())
