Operations on Integers – Subtraction

We have discussed about addition of integers and its representation as chips.  Recall in our previous discussion that a single positive chip added up to a single negative chip is equal to 0. The addition below as we have discussed will give us a notion of how to add signed numbers. Now let us discuss […]
