#### Reversing a subtraction in both the numerator and the denominator of a fraction leaves the fraction's value unchanged

**Description:**

Reversing a subtraction gives the inverse result: ``5-3 = 2; 3-5 = -2``. In a fraction, if both the numerator and the denominator are inverted, the value of the fraction stays the same. So, if we reverse a subtraction in both the numerator and denominator, the value of the fraction is unchanged.
