2 3 - + - 2 3

To simplify the expression \(\frac{2}{3} - \frac{2}{3}\), you will subtract the two fractions. Since the two fractions have the same denominator, you can subtract their numerators directly.

Here are the steps:

1. Write the fractions: \[ \frac{2}{3} - \frac{2}{3} \]

2. Subtract the numerators: \[ = \frac{2 - 2}{3} \]

3. This simplifies to: \[ = \frac{0}{3} \]

4. Since any number divided by a non-zero number is 0, we have: \[ = 0 \]

Thus, the simplified result of the expression \(\frac{2}{3} - \frac{2}{3}\) is \(0\).
