Negative Inverse Calculator

The Negative Inverse Calculator helps you find the negative reciprocal of any number. This is particularly useful in algebra, physics, and engineering where negative reciprocals are common in equations and transformations.

What is Negative Inverse?

The negative inverse (or negative reciprocal) of a number is simply the negative of its reciprocal. For any non-zero number x, the negative inverse is calculated as:

Negative Inverse Formula:

Negative Inverse of x = - (1 / x)

For example, the negative inverse of 2 is -0.5, and the negative inverse of -4 is 0.25. This concept is fundamental in solving equations involving fractions and ratios.

Note: The negative inverse is undefined when x is 0 because division by zero is not allowed in mathematics.

How to Calculate Negative Inverse

Calculating the negative inverse is straightforward once you understand the formula. Here's a step-by-step guide:

Identify the number for which you want to find the negative inverse.
Find the reciprocal of the number by taking 1 divided by the number.
Multiply the reciprocal by -1 to get the negative inverse.

Example Calculation

Let's find the negative inverse of 5:

Reciprocal of 5 = 1 / 5 = 0.2
Negative inverse = -0.2

So, the negative inverse of 5 is -0.2.
