Subtraction is the opposite operation to addition, so can be used to check an addition by subtracting one of the addends (numbers being added together) from the total obtained to see if the other addend results.
This can be used with any two addends including mixed numbers.
Working with mixed numbers is often much easier (especially for multiplication and division) by converting them first to improper fractions, doing the operations and converting any resultant improper fraction back to a mixed number.
It is still a subtraction problem.
those two operations are addition and subtraction.
It depends what type, such as multiplication, division, subtraction, or addition. Be more descriptive!
first add the whole numbers then do simple fraction subtraction
The easiest is to convert both mixed form numbers to improper fractions, do the subtraction (as normal1) and if the result is an improper fraction convert it to mixed form. 1 by converting the improper fractions to equivalent [improper] fractions with a common denominator and subtracting the resultant numerators.
For addition, subtraction, division and multiplication with other fractions

SUBTRACTION: You first turn both mixed numbers into improper fractions. If needed, change the denominators into like denominators. Next, subtract the two improper fractions and reduce if necessary. ADDITION: If needed, turn denominators so they are the same number. Next, add and reduce if necessary.
Yes. The distributive property of multiplication over addition may help.

Convert the fractions into equivalent fractions with the same denominator. In actually adding mixed numbers, it is easier to convert the mixed numbers into improper (top heavy) fractions, do the addition, simplify the resulting fraction and convert any resulting improper fraction back into a mixed number.
you dont
You most likely your node numbers mixed up somewhere, double check them.
For addition and subtraction, nothing. For multiplication, nothing provided you are able to use the distributive property efficiently. For division the mixed fraction should be converted to a top-heavy fraction. Although this can help with the other operations, it is not a "must".
