Expression of type ExprTuple

from the theory of proveit.numbers.multiplication

import proveit
# 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.
%load_expr # Load the stored expression as 'stored_expr'
# import Expression classes needed to build the expression
from proveit import ExprTuple, a, b, c, d, x, y
from proveit.numbers import Mult, subtract

# build up the expression from sub-expressions
expr = ExprTuple(Mult(a, b, subtract(x, y), c, d), Mult(subtract(Mult(a, d, x, b), Mult(a, d, y, b)), c))

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())

\left(a \cdot b \cdot \left(x - y\right) \cdot c \cdot d, \left(\left(a \cdot d \cdot x \cdot b\right) - \left(a \cdot d \cdot y \cdot b\right)\right) \cdot c\right)

justification	if any wrap positions are set, justify to the 'left', 'center', or 'right'	left	left	('with_justification',)
