Addition or Subtraction of fractions is adding or subtracting the numerators for similar fractions and copying the denominator. Express the answer in lowest term. For dissimilar fractions, addition can only be done when changed to similar. This is done by using the least common denominator of the given fractions to be added. Answers are expressed in lowest form.
