+    Function to evaluate the proposition with assumptions.
+
+    Explanation
+    ===========
+
+    This function evaluates the proposition to ``True`` or ``False`` if
+    the truth value can be determined. If not, it returns ``None``.
+
+    It should be discerned from :func:`~.refine` which, when applied to a
+    proposition, simplifies the argument to symbolic ``Boolean`` instead of
+    Python built-in ``True``, ``False`` or ``None``.
+
+    **Syntax**
+
+        * ask(proposition)
+            Evaluate the *proposition* in global assumption context.
+
+        * ask(proposition, assumptions)
+            Evaluate the *proposition* with respect to *assumptions* in
+            global assumption context.
+
+    Parameters
+    ==========
+
+    proposition : Boolean
+        Proposition which will be evaluated to boolean value. If this is
+        not ``AppliedPredicate``, it will be wrapped by ``Q.is_true``.
+
+    assumptions : Boolean, optional
+        Local assumptions to evaluate the *proposition*.
+
+    context : AssumptionsContext, optional
+        Default assumptions to evaluate the *proposition*. By default,
+        this is ``sympy.assumptions.global_assumptions`` variable.
+
+    Returns
+    =======
+
+    ``True``, ``False``, or ``None``
+
+    Raises
+    ======
+
+    TypeError : *proposition* or *assumptions* is not valid logical expression.
+
+    ValueError : assumptions are inconsistent.
+
+    Examples
+    ========
+
+    >>> from sympy import ask, Q, pi
+    >>> from sympy.abc import x, y
+    >>> ask(Q.rational(pi))
+    False
+    >>> ask(Q.even(x*y), Q.even(x) & Q.integer(y))
+    True
+    >>> ask(Q.prime(4*x), Q.integer(x))
+    False
+
+    If the truth value cannot be determined, ``None`` will be returned.
+
+    >>> print(ask(Q.odd(3*x))) # cannot determine unless we know x
+    None
+
+    ``ValueError`` is raised if assumptions are inconsistent.
+
+    >>> ask(Q.integer(x), Q.even(x) & Q.odd(x))
+    Traceback (most recent call last):
+      ...
+    ValueError: inconsistent assumptions Q.even(x) & Q.odd(x)
+
+    Notes
+    =====
+
+    Relations in assumptions are not implemented (yet), so the following
+    will not give a meaningful result.
+
+    >>> ask(Q.positive(x), x > 0)
+
+    It is however a work in progress.

+    Set containing default assumptions which are applied to the ``ask()``
+    function.
+
+    Explanation
+    ===========
+
+    This is used to represent global assumptions, but you can also use this
+    class to create your own local assumptions contexts. It is basically a thin
+    wrapper to Python's set, so see its documentation for advanced usage.
+
+    Examples
+    ========
+
+    The default assumption context is ``global_assumptions``, which is initially empty:
+
+    >>> from sympy import ask, Q
+    >>> from sympy.assumptions import global_assumptions
+    >>> global_assumptions
+    AssumptionsContext()
+
+    You can add default assumptions:
+
+    >>> from sympy.abc import x
+    >>> global_assumptions.add(Q.real(x))
+    >>> global_assumptions
+    AssumptionsContext({Q.real(x)})
+    >>> ask(Q.real(x))
+    True
+
+    And remove them:
+
+    >>> global_assumptions.remove(Q.real(x))
+    >>> print(ask(Q.real(x)))
+    None
+
+    The ``clear()`` method removes every assumption:
+
+    >>> global_assumptions.add(Q.positive(x))
+    >>> global_assumptions
+    AssumptionsContext({Q.positive(x)})
+    >>> global_assumptions.clear()
+    >>> global_assumptions
+    AssumptionsContext()
+
+    See Also

+    ========
+

+    """
+    Base class for mathematical predicates. It also serves as a
+    constructor for undefined predicate objects.
+
+    Explanation
+    ===========
+
+    Predicate is a function that returns a boolean value [1].
+
+    Predicate function is object, and it is instance of predicate class.
+    When a predicate is applied to arguments, ``AppliedPredicate``
+    instance is returned. This merely wraps the argument and remain
+    unevaluated. To obtain the truth value of applied predicate, use the
+    function ``ask``.
+
+    Evaluation of predicate is done by multiple dispatching. You can
+    register new handler to the predicate to support new types.
+
+    Every predicate in SymPy can be accessed via the property of ``Q``.
+    For example, ``Q.even`` returns the predicate which checks if the
+    argument is even number.
+
+    To define a predicate which can be evaluated, you must subclass this
+    class, make an instance of it, and register it to ``Q``. After then,
+    dispatch the handler by argument types.
+
+    If you directly construct predicate using this class, you will get
+    ``UndefinedPredicate`` which cannot be dispatched. This is useful
+    when you are building boolean expressions which do not need to be
+    evaluated.
+
+    Examples
+    ========
+
+    Applying and evaluating to boolean value:
+
+    >>> from sympy import Q, ask
+    >>> ask(Q.prime(7))
+    True
+
+    You can define a new predicate by subclassing and dispatching. Here,
+    we define a predicate for sexy primes [2] as an example.
+
+    >>> from sympy import Predicate, Integer
+    >>> class SexyPrimePredicate(Predicate):
+    ...     name = "sexyprime"
+    >>> Q.sexyprime = SexyPrimePredicate()
+    >>> @Q.sexyprime.register(Integer, Integer)
+    ... def _(int1, int2, assumptions):
+    ...     args = sorted([int1, int2])
+    ...     if not all(ask(Q.prime(a), assumptions) for a in args):
+    ...         return False
+    ...     return args[1] - args[0] == 6
+    >>> ask(Q.sexyprime(5, 11))
+    True
+
+    Direct constructing returns ``UndefinedPredicate``, which can be
+    applied but cannot be dispatched.
+
+    >>> from sympy import Predicate, Integer
+    >>> Q.P = Predicate("P")
+    >>> type(Q.P)
+    <class 'sympy.assumptions.assume.UndefinedPredicate'>
+    >>> Q.P(1)
+    Q.P(1)
+    >>> Q.P.register(Integer)(lambda expr, assump: True)

+    interval `(-\infty, \infty)`.  Note that, in particular the
+    infinities are not real. Use ``Q.extended_real`` if you want to
+    consider those as well.
+
+    A few important facts about reals:
+
+    - Every real number is positive, negative, or zero.  Furthermore,
+        because these sets are pairwise disjoint, each real number is
+        exactly one of those three.
+
+    - Every real number is also complex.
+
+    - Every real number is finite.
+
+    - Every real number is either rational or irrational.
+
+    - Every real number is either algebraic or transcendental.
+
+    - The facts ``Q.negative``, ``Q.zero``, ``Q.positive``,
+        ``Q.nonnegative``, ``Q.nonpositive``, ``Q.nonzero``,
+        ``Q.integer``, ``Q.rational``, and ``Q.irrational`` all imply
+        ``Q.real``, as do all facts that imply those facts.
+
+    - The facts ``Q.algebraic``, and ``Q.transcendental`` do not imply
+        ``Q.real``; they imply ``Q.complex``. An algebraic or
+        transcendental number may or may not be real.
+
+    - The "non" facts (i.e., ``Q.nonnegative``, ``Q.nonzero``,
+        ``Q.nonpositive`` and ``Q.noninteger``) are not equivalent to
+        not the fact, but rather, not the fact *and* ``Q.real``.
+        For example, ``Q.nonnegative`` means ``~Q.negative & Q.real``.
+        So for example, ``I`` is not nonnegative, nonzero, or

+
+    Unlike :func:`~.simplify` which performs structural simplification

+
+    Refining boolean expression involves reducing it to ``S.true`` or

+class BinaryRelation(Predicate):
+    """
+    Base class for all binary relational predicates.
+
+    Explanation
+    ===========
+
+    Binary relation takes two arguments and returns ``AppliedBinaryRelation``
+    instance. To evaluate it to boolean value, use :obj:`~.ask()` or
+    :obj:`~.refine()` function.
+
+    You can add support for new types by registering the handler to dispatcher.
+    See :obj:`~.Predicate()` for more information about predicate dispatching.
+
+    Examples
+    ========
+
+    Applying and evaluating to boolean value:
+
+    >>> from sympy import Q, ask, sin, cos
+    >>> from sympy.abc import x
+    >>> Q.eq(sin(x)**2+cos(x)**2, 1)
+    Q.eq(sin(x)**2 + cos(x)**2, 1)
+    >>> ask(_)
+    True
+
+    You can define a new binary relation by subclassing and dispatching.
+    Here, we define a relation $R$ such that $x R y$ returns true if
+    $x = y + 1$.
+
+    >>> from sympy import ask, Number, Q
+    >>> from sympy.assumptions import BinaryRelation
+    >>> class MyRel(BinaryRelation):
+    ...     name = "R"
+    ...     is_reflexive = False
+    >>> Q.R = MyRel()
+    >>> @Q.R.register(Number, Number)
+    ... def _(n1, n2, assumptions):
+    ...     return ask(Q.zero(n1 - n2 - 1), assumptions)
+    >>> Q.R(2, 1)
+    Q.R(2, 1)
+
+    Now, we can use ``ask()`` to evaluate it to boolean value.
+
+    >>> ask(Q.R(2, 1))
+    True
+    >>> ask(Q.R(1, 2))
+    False
+
+    ``Q.R`` returns ``False`` with minimum cost if two arguments have same
+    structure because it is antireflexive relation [1] by
+    ``is_reflexive = False``.
+
+    >>> ask(Q.R(x, x))
+    False
