Expression of type ExprTuple

from the theory of proveit.numbers.multiplication

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

# import Expression classes needed to build the expression
from proveit import ExprTuple, a, b, c, d
from proveit.numbers import Exp, Neg, four, frac, one, three, two

# build up the expression from sub-expressions
expr = ExprTuple(frac(four, three), Exp(d, two), b, a, c, Exp(b, Neg(frac(one, two))))

expr:

# check that the built expression is the same as the stored expression
assert expr == stored_expr
assert expr._style_id == stored_expr._style_id
print("Passed sanity check: expr matches 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())
