you take away one of the whole number=then you add or subtract your fractions=
Oh, dude, renaming the fractional sum when adding mixed numbers is like wearing a hat indoors - it's not necessary, but it might make things a bit fancier. Technically, you can add mixed numbers without renaming the sum, but it can make the math simpler and easier to understand. So, like, you do you - rename or not, it's all good.
Mixed numbers have fractional parts that must be compared; whole numbers do not.

Mixed numbers and integers are different things.
You cannot. Whole numbers and mixed numbers are two different subsets of the set of numbers.
when you add mixed numbers you have a whole number but adding fraction does not.
if you have mixed numbers you make them into improper fractions before you multiply
the fractions have different denominators
If the mixed number is x y/z then the numerator is (x*z + y)
they are the same because they both have whole numbers
You tell whats the same and different.
