Editing How to Add and Subtract Like Fractions (section)

== Important Considerations: ==

1. '''Simplification''': After adding or subtracting, always check if the resulting fraction can be simplified by finding common factors between the numerator and denominator.

2. '''Improper Fractions''': The result may be an improper fraction (numerator larger than denominator). You can leave it as is or convert it to a mixed number.

3. '''Negative Fractions''': When subtracting, if the result is negative, place the negative sign in front of the fraction.

   Example: \[ \frac{1}{4} - \frac{3}{4} = \frac{1 - 3}{4} = -\frac{2}{4} = -\frac{1}{2} \]

4. '''Mixed Numbers''': If working with mixed numbers, convert them to improper fractions first, then add or subtract as usual.

   Example: \[ 2\frac{1}{3} + 1\frac{2}{3} = \frac{7}{3} + \frac{5}{3} = \frac{12}{3} = 4 \]

5. '''Zero''': Adding or subtracting zero to/from a fraction leaves the fraction unchanged.
