Positive and negative integers are opposite each other.
It is 9.
A positive integer would just be a regular number like 2. A negative integer is a negative number like -2. (2 below zero)
A deposit is represented by a positive number, meaning an addition to your balance. There may be a situation where an Invoice is a positive amount, and this would indicate that an invoiced amount has been reversed/removed, therefore adding the funds back into your deposit account balance and available to be spent.
Do you mean 2 x (-3)? If that's what you mean, it's 6, positive.
Positive and negative integers are opposite each other.
All positive integers are all greater than negative integers.
An integer is any positive or negative whole number
No. A mean is another word for average. Can be negative, positive, or zero. As long as it adds 2 or more integers and divides it by the number of integers.
Positive integers. Or non-negative integers. No point in arguing, simply ask your teacher which one they mean.
By adding whatever you mean with "integers of a number".
"Whole number" may refer to an integer, or it may refer to a POSITIVE integer. Because of this ambiguity in the definition, it is preferable to talk about integers, positive integers, or non-negative integers, depending on what you mean.
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.
Integers are whole numbers with no fractional part, for example: 24, 3, 1, 0, -5, 376 and 12345 are all integers. As you can see, the set of integers includes zero as well as positive and negative numbers.
No. For example, 2 + 3 = 5 which is positive, and 2 + (-2) = 0 which is neither positive nor negative. Well, that completely discredits my 4th grade math book that said any number that is not negative IS positive. Therefore, zero is by default a positive number. However, the sum of two negative integers will always be negative. Adding a negative integer decreases the value of the result and given that both integers are negative implies that the sum will be negative. "Implies"? you say. Do you have no conviction? Cannot you say 'determines' when it is obvious? "not obvious"? you say, Then does that mean the sum of 2 negative numbers MIGHT not be negative? See, this is what happens when a 5th grade question is answered by someone with superior attitude.
The answer will depend on what you mean by number: integers, rationals, reals, complex numbers, etc.
An integer is a whole number (positive, negative, or zero), and does not include a fractional or decimal part. Integers are 0, 1, -1, 2, -2, 3, -3, etc.
