That would be -n. Note that if n is positive, -n is negative, whereas if n is negative, -n will be positive.

When can you say that a given real number is irrational?
A real number is an irrational number if it cannot be expressed as a fraction a/b, where a and b are integers. Most real numbers are irrational. The most well known irrational numbers are π and √2. The inverse condition are called the rational numbers.
Is subtraction an identity property?
Subtraction is not an identity property but it does have an identity property. The identity is 0 and each number is its own inverse with respect to subtraction. However, this is effectively the same as the inverse property of addition so there is no real need to define it as a separate property.
Why 0 does not have a multiplicative inverse?
As n gets very small, 1/n goes towards infinity. A multiplicative inverse of 0 would be some number x, such that 0x=1. This is impossible with the real numbers we use, since 0x=0 for any number x. One might be tempted to invent a new number (calling it "infinity", "nullity", or any other name) that would be the inverse of 0. Of course, then you're not dealing with real numbers anymore, you're dealing with real numbers plus this invented number. There are serious issues even with this approach. Again, let x be this "multiplicative inverse of 0". Then 0*1=0 and 0*2=0. So 0*1 = 0*2. Multiply both sides by x to get x*0*1 = x*0*2. Since x*0 is 1, this means 1*1 = 1*2. So 1=2, which is an absurd conclusion. As you can see, there are good reasons not to allow a multiplicative inverse for 0 - it breaks all the laws of multiplication we're accustomed to.
How do you write an irrational number in algebra?
There is no representation for irrational numbers: they are represented as real numbers that are not rational. The set of real numbers is R and set of rational numbers is Q so that the set of irrational numbers is the complement if Q in R.
Which real number contains additive inverses for all its elements?
The question is confusing. The additive inverse of a real number is the same number with the sign changed. For example, the additive inverse of -5 is +5 (or simply 5); the additive inverse of 7 (which is the same as +7) is -7.
What is a example of addition inverses in math?
The additive inverse of a real number is the number that when added to it equals zero, the identity element for addition. That is, the additive inverse of any real number x is -x.
What is the sum of a real number and is additive inverse?
The sum is zero.
How do you find the additive inverse of a complex number?
You take the additive invers of the real and of the imaginary part. For instance, the additive inverse of: (3 - 5i) is (-3 + 5i).You take the additive invers of the real and of the imaginary part. For instance, the additive inverse of: (3 - 5i) is (-3 + 5i).You take the additive invers of the real and of the imaginary part.

What does additive inverse look like?
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. This number is also known as the opposite. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive.
How is the additive inverse property related to the additive identity property?
They have no real relations ofther than being mathmatical properties The additive identity states that any number + 0 is still that number; a+0 = a The additive inverse property states that any number added to its inverse/opposite is zero; a + -a = 0
What is additive inverse of 0?
This number is also known as the opposite (number), sign change, and negation. For a real number, it reverses its sign: the opposite to a positive number is negative, and the opposite to a negative number is positive. Zero is the additive inverse of itself.
What is a real number a the number that is the same distance from 0 as a on the opposite side of the number line?
The additive inverse.
Is zero is not considered a real number?
Wrong! Not only is zero a real number, but it is the additive identity for the set of integers, rational numbers as well as real numbers.
How do you use additive inverse in the real world?
The additive inverse is used to solve equations; equations, in turn, are used to model many real-world situations.
Which property of real numbers states that a number added to its opposite results in 0?
The existence of an additive inverse.
What is the additive inverse of 6 plus 4i?
The additive inverse of 6+4i is -6-4i since their sum is 0. It is analogous to real numbers where the additive inverse of 6 is -6 since 6+-6 =6-6=0 In the case of complex numbers, we add them by adding the real parts and then adding the imaginary parts. So to find the complex additive inverse of a+bi, we find the inverse of a which is -a and of bi which is -bi and so the additive inverse is -a-bi
