The inverse of addition is subtraction and vice versa. In other words, if a number, like 5, is added to another number, like 7 (to get 7+5=12), then the way to get back to the original number, 7, is to subtract 5 from 12. Similarly, if a number, like 5, is subtracted from another number, like 7 (to get 7-5=2), then the way to get back to the original number, 7, is to add 5 to 2. Similarly, multiplication and division are also inverses of each other.
