All rational numbers, with the exception of zero (0), have a multiplicative inverse. In fact, all real numbers (again, except for zero) have multiplicative inverses, though the inverses of irrational numbers are themselves irrational. Even imaginary numbers have multiplicative inverses (the multiplicative inverse of 5i is -0.2i - as you can see the inverse itself is also imaginary). Even complex numbers (the sum of an imaginary number and a real number) have multiplicative inverses (the inverse of [5i + 2] is [-5i/29 + 2/29] - similar to irrational and imaginary numbers, the inverse of a complex number is itself complex). The onlynumber, in any set of numbers, that does not have a multiplicative inverse is zero.

This may refer to the additive inverse, or to the multiplicative inverse. To find the additive opposite (negative) of a number multiply it by -1 The only number without an opposite is 0. To find the multiplicative inverse (reciprocal), make the number the numerator of a fraction (e.g., the reciprocal of 3 is 1/3). The additive inverse of 4 is minus 4 (the idea is to have two numbers that add up to zero), whereas the multiplicative inverse of 4 is 1/4 (the idea is to have two numbers whose product is 1).

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

The additive inverse is the sum of two numbers that will equal zero. The additive inverse of -18 is 18.

The inverse function of multiplication is division.

An inverse, without any qualification, is taken to be the multiplicative inverse. is The inverse of a number, x (x not 0), is 1 divided by x. Any number multiplied by its inverse must be equal to 1. There is also an additive inverse. For any number y, the additive inverse is -y. And the sum of the two must always be 0.

A number and its additive inverse add up to zero. If a number has no sign, add a "-" in front of it to get its additive inverse. The additive inverse of 5 is -5. The additive inverse of x is -x. If a number has a minus sign, take it away to get its additive inverse. The additive inverse of -10 is 10. The additive inverse of -y is y.

Yes, and for any non-zero rational x, the multiplicative inverse is 1/x.

The additive inverse of the numbers 18 and 23 is 1. This is taught in math.

A multiplicative inverse for 2 numbers exists if the 2 numbers are coprime, i.e. their greatest common divisor (or gcd) is 1. However, if your question refers to just a singular number, virtually all real numbers (with the exception of zero) have a multiplicative inverse.

The opposite of a number can be itself when its the sum of two numbers and we only be switching the positions of inputs and the order is changed. The opposite of opposite of negative number is opsitive number Okay!

change it to an improper fraction and then do it

multiplicative inverse

Every non zero number has a multiplicative inverse, which is 1 divided by that number. This stands for both real and complex numbers. This can be proved by letting x=some non zero number. x*(1/x)=x/x=1, therefore the multiplicative inverse of x is 1/x.

When you add a number and its additive inverse, for example x+(-x), you would get 0 as an answer no matter what the number is. When you multiply a number and its reciprocal or multiplicative inverse, for example x*(1/x), you would always get 1 as an answer.

They are, respectively, the multiplicative and additive identities for the field of numbers.

No. It has a different additive inverses for each element.

As far as positive numbers are concerned, the additive inverse of a positive number is a negative number with the same magnitude (i.e. the additive inverse of 5 is -5). It would be wrong to simply say that "negative" and "additive inverse" are correct, because the additive inverse of a negative number is a positive number.

The additive inverse of a number is the number with the same magnitude but with the sign changed. It is a number such that the two numbers added together make zero (the additive identity).

A number's reciprocal could be called a multiplicative inverse.

Definition for additive inverse:Web definitions:(mathematics) one of a pair of numbers whose sum is zero; the additive inverse of -5 is +5. -56 + 56 = 0SO the additive inverse of 56 is -56 or negative 56

A pair of numbers whose sum is zero. The additive inverse of 10 is -10 because 10+(-10) = 0.
