Webcomplement. Remark x ∧y 0 iff y ≤x∗. That is, the complement x∗of x is the largest element whose meet with x is zero. Similarly, if x ∨y 1,theny≥x∗, that is, x∗is the smallest element whose join with x is one. Proof Recall that in any lattice, x ≤y is equivalent to x ∧y x, as well as to x ∨y y.Now, from x ∧y 0 we get x ∧y ∨y∗ 0 ∨y∗ y∗. WebDefine ∗ on Z by a∗b=a−b+ab .

"WebAnswer (1 of 5): Yes it certainly does, because for any pair of positive integers a and b you have a well-defined rule that determines a third such integer.

WebThen there exists a unique element b∈ G such that b∗a= a∗b= e. Proof. By the inverse element axiom, such an element bexists. Let c ∈ Gsuch that c∗a= a∗c= e. Then c= c∗e= c∗(a∗b) = (c∗a)∗b= e∗b= b, by associativity and by the property of e. This unique inverse element of ais typically denoted as a−1. WARNING: when the WebAnswer (1 of 3): It is not because a binary operation on a set takes two elements of that set and produces an element of that set as well. This operation fails to do that in the case that the subtraction of two positive integers happens to be negative. For example 2 and 5 are members of Z+. But...
