These are drills to help you learn how to subtract, but I think the makers of this album took the word "drill" way too seriously. This teaches subtraction tables with a lady singing over the same four bars of music over and over and OVER except for a small bit at the beginning and the end of each side. I see this being used less for learning subtraction and more for torturing roommates or coercing information from enemy spies. I will not be held responsible as to how you use it!
