Is subtraction an identity property?
Subtraction is not an identity property but it does have an identity property. The identity is 0 and each number is its own inverse with respect to subtraction. However, this is effectively the same as the inverse property of addition so there is no real need to define it as a separate property.
Give an example to show that subtraction is not associative?
The associative property refers to mathematical expressions where the order of the number is totally interchangeable and will still yield the same answer. Changing the order of a subtraction problem will give you a different answer. For example, 4 - 1 = 3. When switched, 1 - 4 does not equal 3. It equals -3.
How are addition and subtraction mathematically connected?

What is the result of when you get when you one number by another?

How are addition and subtraction stories alike?
Addition and subtraction can be thought of as the same thing because subtracting a negative number is the same as adding it and adding a negative number is the same as subtracting it.
The similarities of subtraction and addition?
It is tough to find similarities, but I can think of couple listed below. 1. Both Addition and Subtraction can only be done on numbers. 2. Subtraction is also addition with negative number. Hope this helps.

What is real number operations?
multiplication-addition-subtraction-division
What is the number zero called for addition and subtraction?

Are real numbers closed under addition and subtraction?
Real numbers are closed under addition and subtraction. To get a number outside the real number system you would have to use square root.
Why when subtracting a negative number must you change the subtraction sign to an addition sign?
Because a negative negative is the same a a positive, and because of the definition of subtraction and addition.
