Operations with Mixed Numbers
Addition and Subtraction
When adding or subtracting mixed numbers, we generally add or subtract each part -- add/subtract fraction (sometimes with conversion to common denominator) and add/subtract whole numbers. Sometimes, we may need to regroup fractions or "borrow" from whole numbers -- much like regrouping or borrowing when adding multi-digit numbers.
Alternatively, we can convert to improper fractions and add/subtract like regular fractions.
Multiplication and Division
When multiplying or dividing mixed numbers, we can convert to improper fractions and proceed as usual.
