Yes because you are always adding.
It doesn't always. 3 - (-3) = 6
No, the set of negative integers is not closed under addition. When you add two negative integers, the result is always a negative integer. However, if you add a negative integer and a positive integer, the result can be a positive integer, which is not in the set of negative integers. Thus, the set does not satisfy the closure property for addition.
Yes, because subtrating a negative number is the same thing as adding a positive number.
As long as the negative integer is greater than the positive integer, a negative integer will result from addition, subtraction, multiplication, and division.
The multiplication rule of thumb always states that a negative number times a negative number results in a positive number. Since an even number is always divisible by two, any value raised to an even integer power will result in a positive number. However, a basic proof is presented as follows: (-A) * (-A) = A^2 ((-A) * (-A)) ^ 2 = ((-A * -A) * (-A * -A)) = A^2 * A^2 = A ^ 4 ...

False. Counterexample: -1 - (-2) = -1 + 2 = 1.

All negative integers, when multiplied by a positive integer, or vice versa, will result in a negative integer. I. E. 5*-5=-25
When two negative integers are added, the result is always a negative integer. This is because adding two negative numbers means you are combining their absolute values and keeping the negative sign. Therefore, it is impossible to obtain a positive integer from the sum of two negative integers.
Example 5 × −6 = −30 therefore it is negative.
If you divide a positive number (it doesn't really matter if it is an integer or a fraction) by a negative number, the result is negative.
When a negative number is raised to an even power the result is a positive number
A rational number is always the result of dividing an integer when the divisor is nonzero.
