6 - 8 = -2 is one possible answer.

There are infinitely many possible answers. For example, (-3) - (-5) = 2.

Integers are any positive or negative whole numbers. Subtraction involves taking the subtrahend from the minuend.You take the value of the first, and take it away from the second, and depending on the signs that are similar (positive/negative) they can cancel and override each other.

they both have something to do with positive and negative

any time the 2nd neg. has a larger absolute value than the 1st ex: (-3) - (-4) = +1

yes, because an integer is a positive or negative, rational, whole number. when you subject integers, you still get a positive or negative, rational, whole number, which means that under the closure property of real numbers, the set of integers is closed under subtraction.

It can be a problem to do with adding or subtracting or exponents.

If you interpret "whole numbers" as "integers", then yes. If you interpret "whole numbers" as "non-negative integers", then no.

No, a constant cannot be considered a polynomial because it is only a single term. A polynomial is defined as an expression that consists of the variables and coefficients that involves only the operations of subtraction, addition, multiplication, and the non-negative integer exponents.

turn the subtraction sign into an addition sign and the 3 into a negative: 1+-3=-2

To be closed under an operation, when that operation is applied to two member of a set then the result must also be a member of the set. Thus the sets ℂ (Complex numbers), ℝ (Real Numbers), ℚ (Rational Numbers) and ℤ (integers) are closed under subtraction. ℤ+ (the positive integers), ℤ- (the negative integers) and ℕ (the natural numbers) are not closed under subtraction as subtraction can lead to a result which is not a member of the set.

There is no specific name unless the exponents can only be non-negative integers. In the latter case, it is a quadratic expression.

1 No. 2 No. 3 Yes.

Because the set is not closed under subtraction. This led to the set being extended to included negative integers.

The rules for addition are as follows:The sum of two negative integers is a negative integerThe sum of two positive integers is a positive integerThe rules for subtraction are as follows:If they are two positive numbers, do it normallyIf there is a negative and a positive ,change it to addition and switch the SECOND integer sign

The term "whole numbers" is ambiguous; it may refer either to integers, or only to positive integers (perhaps including zero). The set of integers is closed under subtraction, that means, you can subtract any number from any other number. This is not possible in the set of counting numbers (non-negative integers).

Unfortunately, the term "whole numbers" is somewhat ambiguous - it means different things to different people. If you mean "integers", yes, it is closed. If you mean "positive integers" or "non-negative integers", no, it isn't.

If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.

There is no such thing as a negative set of integers. There can be a set of negative integers, but that is not the same thing. And even that does not make sense.There is no such thing as a negative set of integers. There can be a set of negative integers, but that is not the same thing.

if its a positive plus a negative (ie. 8+ -3) you can substitute the plus, negative(ie. 8+ -3)(+ -) for a subtraction sign (ie. 8-3) and you will come up with the same answer

No, not counting zero,the difference is always positive since minus a minus is plus

An integer is either positive (non-negative), or negative, or zero. There are no negative non-negative integers.
