It is true.

False - if the sentence is meant to be exhaustive. Integers can be positive or negative OR ZERO.

False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.False. Either the product or the quotient of two negative numbers is positive.

This statement is true when the two integers are positive, or when the two integers are negative.

It is false. It does not include negative fractional numbers.

yes the answer is always a positive

False.

That is false. A negative times a negative is always a positive. Since absolute numbers are always positive if you make it negative that is not correct.

Yes. Natural numbers are the counting numbers we use. Integers however contains also the negative values. So yes, natural numbers are integers, but the converse is not true though: integers are counting numbers is false.

It is true.

That is false. This type of statement is only true for prime numbers, not for compound numbers such as 6. Counterexample: 2 x 3 = 6

No, that is not true.

True. If the equation is (-4)divided by (-8) the quotient will be +2 because 8 divided by 4=2 and the two integers are the same, so it's positive. The same goes for multiplying integers.

Yes, multiplying a Positive value by a Negative value always yields a Negative product.

One possible conjecture is that the product of two odd integers is 8. A conjecture does not have to be true, nor does it have to be sensible. It must be testable, though. Many conjectures were initially thought to be sensible and true but later proven to be false. And when the false nature is fully understood, in retrospect they no longer appear sensible either!

False. The natural numbers are the counting numbers: 1, 2, 3, ... which are the positive integers; -7 is a negative integer and so not one of them.

Yes, it is true.

The statement is false.

No, integers are positive and negative whole numbers

True

Yes.

if by Numbers you mean Integers, then the answer is TRUE. if it is real numbers, then it is false.

True

It is true.

Yes, it is true.
