WebThe closure property of addition states that when any two elements of a set are added, their sum will also be present in that set. The closure property formula for addition for a given set S is: ∀ a, b ∈ S ⇒ a + b ∈ S. Here are some examples of sets that are closed under addition: Natural Numbers (ℕ): ∀ a, b ∈ ℕ ⇒ a + b ∈ ℕ

WebThe purpose of this warm-up is to elicit the idea that integers can be combined in ways that result in integers, or in ways that do not result in integers. This will be useful when students experiment to find out which operations integers are closed under in a later activity. WebThe addition (+) and multiplication (×) operations on natural numbers as defined above have several algebraic properties: Closure under addition and multiplication: for all natural numbers a and b, both a + b and a × b are natural numbers. Associativity: for all natural numbers a, b, and c, a + (b + c) = (a + b) + c and a × (b × c) = (a × ...
