What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
What must you do first before adding or subtracting unlike fractions?
you must make the fractions equivalent and with the same denomenator
When adding or subtracting fractions you must get a?
A Common Denominator
How is adding fractions like adding whole numbers... How is it different?
Similarities: the sum does not depend on which number you start with (distributive)Differences: you must find a common denominator for the fractions (whole numbers have a common denominator [1]

Do you change fractions 2 like fractions when adding them?
Yes, you must.
What you must have when you adding fractions?

Why must you find a common denominator before adding fractions?
You can only add like to like. There is no mechanism for adding different types of fraction.
Do the adding fractions rule apply to subracting?
Yes inasmuch that the denominators of the fractions must be common to each other.
Can you simplify fractions when adding?
Yes but they all must have the same common denominator
