Expression of type ExprTuple

from the theory of proveit.numbers.addition

proveit.defaults.automation = False # This will speed things up.
proveit.defaults.inline_pngs = False # Makes files smaller.

from proveit.numbers import Add, Mult, Neg, one, three, two

# build up the expression from sub-expressions
expr = ExprTuple(Add(Mult(two, b), Mult(three, b), b, Neg(b)), Mult(Add(two, three, one, Neg(one)), b))

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

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

\left(\left(2 \cdot b\right) + \left(3 \cdot b\right) + b - b, \left(2 + 3 + 1 - 1\right) \cdot b\right)
