Title: adding and subtracting mixed numbers 0.5 and 1

Per Trello Card #366

Add 2 problem types to adding and subtracting mixed numbers 0.5 and 1

1) Subtract a mixed number from an integer (add this to adding and subtracting mixed numbers 0.5)

2) Subtract mixed numbers with borrowing (e.g., 4 1/8 - 2 3/4) - in hints, show 2 ways of doing this: a) convert both to improper fractions, b) turn 4 1/8 into 3 + 8/8 + 1/8 or 3 + 9/8 before subtracting

Should be all set!
