When you combine any two numbers in a set the result is also in that set.
e.g. The set of whole numbers is closed with respect to addition, subtraction and multiplication. i.e. when you add, subtract or multiply two numbers the answer will always be a whole number.
But the set of whole numbers is NOT closed with respect to division as the answer is not always a whole number e.g. 7÷5=1.4 The answer is not a whole number.
The answer depends on the context. Sets (or intervals) can be open or closed, or semi-open. In a different context, sets can be closed (or not) with respect to some operation (addition, division, something else) defined on element of the set. Without that context, it is not possible to answer the question.
Examples of the purpose of closure in math
It stands for Tamera Hope I helped ^_^ If not I'm sorry :(
The main difference between Kaleen closure and positive closure is; the positive closure does not contains the null, but Kaleen closure can contain the null.
it is the closure of the set
No. Closure is the property of a set with respect to an operation. You cannot have closure without a defined set and you cannot have closure without a defined operation.
Examples of the purpose of closure in math
the principle of proximity
In the context of sets, closure implies that the limiting value of the extremum of the set is itself an element of the set.
Math does not help principle.
The principle of continuity states that when things are connected, people tend to see them as one object, not their various parts. The principle of closure states that the person's mind tends to see complete figures even if they are incomplete.

It came from Gestaltist Principle of The law of closure: People tend to fill in missing pieces to form a complete picture. However, it is back formation from closure to cloze, not cloze method though.

I=prt Switch the principle with the interest. Then work the equation out.
Math is not local, it is universal. Your question is incoherent.
The sum or product of two real numbers is a uniquereal number, like 2+3 is always 5... ;~}
You use it all the time, without thinking about it: if you do an addition or multiplication, you assume that there is a solution.
