As a seasoned tutor registered on UrbanPro.com, I'm here to address a mathematical query regarding the reciprocal of a number.
Understanding the Question: The question posits, "The reciprocal of the reciprocal of a number is _________." Let's break down the concept and arrive at a clear answer.
Reciprocal Basics:
Answering the Question: The reciprocal of the reciprocal of a number is the number itself.
Explanation:
Therefore, the reciprocal of the reciprocal of any non-zero number 'a' is 'a' itself.
Conclusion: In the realm of reciprocals, understanding that the double reciprocal brings us back to the original number is fundamental. This concept is pivotal in various mathematical applications and problem-solving.

Hello and thank you for reaching out to me, an experienced tutor registered on UrbanPro.com. I understand that you are seeking guidance on the rational number that is neither positive nor negative. Let me provide you with a clear and concise explanation.
The rational number that is neither positive nor negative is 0.
Zero as a Neutral Value: Zero is unique among rational numbers as it represents the neutral point on the number line.
Not Positively or Negatively Charged: Unlike positive rational numbers, such as 1, 2, 3, etc., and negative rational numbers, such as -1, -2, -3, etc., zero does not carry a positive or negative charge.
Position on the Number Line: When plotted on the number line, zero is positioned at the origin, indicating an absence of positive or negative magnitude.
In conclusion, the rational number 0 is neither positive nor negative. It holds a special place as the neutral element in the realm of rational numbers. If you have any further questions or if there's anything else I can assist you with, feel free to ask.

As a seasoned tutor registered on UrbanPro.com, I understand the importance of providing clear and concise explanations to students. Let's delve into the question at hand:
Rational numbers are those that can be expressed as the quotient or fraction p/q, where p and q are integers and q is not equal to zero. Examples include 1/2, -3/4, and 7.
The additive inverse of a number is the value that, when added to the original number, results in a sum of zero. For any rational number 'a,' its additive inverse is '-a.'
To find a rational number that is equal to its additive inverse, we can set up an equation:
a+(−a)=0a+(−a)=0
The only rational number that satisfies this equation is zero (0).
In conclusion, among all rational numbers, zero is the unique number that is equal to its additive inverse. This understanding aligns with the fundamental properties of rational numbers and their additive inverses. If you have further questions or need additional clarification, feel free to reach out for more personalized assistance.
