Understanding the Mathematical Expression: A Deep Dive into rac{2}{3} = –rac{2}{3} – rac{–rac{2}{3}: A Step-by-Step Breakdown

Maths can sometimes feel like a puzzle, especially when expressions involving fractions and negative signs appear—like rac{2}{3} = –rac{2}{3} – rac{–rac{2}{3}. At first glance, this equation may seem confusing, but with the right breakdown, it becomes a clear and valuable learning moment. In this article, we’ll explore what this equation means, how to solve it step-by-step, and why mastering such expressions is essential for stronger foundational math skills.

What Does the Expression Mean?

The equation –rac{2}{3} – (–rac{2}{3}) involves two key parts:

rac{2}{3): a positive fraction of two-thirds
– (–rac{2}{3}: the negation of –rac{2}{3}, which simplifies to += rac{2}{3}

This expression symbolizes a mathematical balancing act involving opposing signs and halves.

Step-by-Step Simplification

Let’s break it down:

Original Expression: – rac{2}{3} – (– rac{2}{3)

Step 1: Handle the double negative Subtracting a negative is the same as adding a positive: – (– rac{2}{3}) = + rac{2}{3} Thus, the equation becomes: – rac{2}{3} + rac{2}{3}

Step 2: Combine like terms Both terms are rac{2}{3}, so: (–1 + 1) × rac{2}{3} = 0 × rac{2}{3} = 0
