__Adding Fractions:__

When you add fractions you only add the numerators (top numbers). You can only add fractions that have the same denominators. When you have fractions with different denominators you have to find the common denominator between the 2 or more fractions. Denominators always stay the same. When you have whole numbers you have to add them as well.

__Subtraction:__

When you subtraction fractions you can only subtract fractions with the same denominator. When you subtract fractions only subtract the numerators. When you have fractions with different denominators you have to find the common denominator between the 2 or more fractions. Denominators always stay the same way. You can only subtract a smaller numerator from a bigger numerator.
