What does these symbols "∔" and "∸" in mathematics means? Example of the sentences for ∔: A linear manifold X of the inner product space (X,[·,·]) is a direct summand of X^0 (i.e. X = L∔X^0 for some linear manifold L in X) if and only if it is maximal nondegenerate. Example of the sentences for ∸: Write a formal register machine that computes the function f(x,y)=2x ∸ 2y.

From this document: "the binary operator ∸ is defined by x∸y = x – y if x > y, and 0 otherwise"
From this document: "Here, ∔ denotes the direct sum of two linearly independent linear manifolds, see the next subsection for a more detailed explanation." This is on page 45.
