Convention 0
(Multiplicative notation)
Let X≠∅ be a D11: Set and let f:X×X→Y be a D554: Binary operation on X. If x,y∈X, then the convention in multiplicative notation is to denote the element f(x,y) by xy.

Convention 1
(Additive notation)
Let X≠∅ be a D11: Set and let f:X×X→Y be a D554: Binary operation on X. If x,y∈X, then the convention in additive notation is to denote the element f(x,y) by x+y.
