Adding and Subtracting Like Fractions: For fractions with the same denominator, add or subtract the numerators, then simplify the result if possible.

Adding and Subtracting Unlike Fractions: Find the lowest common denominator, convert both fractions, then add or subtract the numerators.

Proper, Improper, and Mixed Fractions: Proper fractions have a smaller numerator than denominator, while improper fractions have a larger or equal numerator. Mixed fractions combine a whole number with a proper fraction.

Converting Improper Fractions to Mixed Numbers: Divide the numerator by the denominator to get a quotient (whole part) and remainder (numerator), and keep the original denominator.
