That would be the set of all non-zero numbers. If by number you actually meant whole numbers, that is integers, then it would be the set of all non-zero integers. They are also called Additive Inverses. For example, -5 is the additive inverse of 5, because 5 + (-5) = 0. Similarly, 7 is the additive inverse of -7 because (-7) + 7 = 0.
Every positive rational number and its negative are the two square roots of the same positive rational number.
Yes, all integers are considered to be real numbers.
A negative integer. Every time.
Yes. The letter i denotes the value of the "positive square root" of -1. So i² = -1. But also (-i)² = -1 as well. Remember that for every number there is a "positive" and "negative" square root. So if you want the square root of -4, you can do this: -4 = (-1)(4). So sqrt(-4) = sqrt[(-1)(4)] = sqrt(-1)*sqrt(4) = i*2 or -i*2. We usually write these as 2i and -2i.
true because if it is an absolute integer it cant be negative and 0 is nor a negative number or positive. so it would always be positive. Example- l-7l its absolute value would be 7, or l4l its absolute value would be 4.
Every positive rational number and its negative are the two square roots of the same positive rational number.
It is because of the way in which positive and negative numbers are defined.
The 2 positive integers don't affect the sign. Every time you multiply by a negative number, the sign changes, so you have negative, positive, negative, positive... Since the number of negative numbers is odd, the end result is negative.The 2 positive integers don't affect the sign.

No, a whole number can be negative (or zero).
It is a negative number, because every pair of negative factors makes a positive, and you have 10 pairs plus one left over.
The square of every positive or negative even whole number is a positive even whole number. The square of every positive or negative odd whole number is a positive odd whole number. There are an infinite number of each kind.
The additive inverse of EVERY positive rational number is a negative number.
It depends on what you mean by an opposite. Every real number has an additive opposite but 0 does not have a multiplicative opposite.
No because they can also be positive numbers
Well, honey, the square root of a negative number like -9 isn't a real number because in the real number system, the square root of a negative number isn't defined. You gotta step into the world of complex numbers if you wanna play with those imaginary roots. So, in short, the square root of -9 is as real as a unicorn riding a rainbow.
No, not every negative number is an integer. For example, -11/2 is not an integer. However, -1, -2, -3, and so on, are negative integers. Perhaps that is what you meant to ask. The negative of every positive integer is a negative integer.
Every positive integer has two square roots, a positive square root and a negative square root. This is because, just like a positive number multiplied by a positive number is equal to a positive number, a negative number multiplied by a negative number is equal to a positive number. Therefore, rounded to two decimal places, the positive square root is equal to 7.28, and the negative square root is -7.28.
