In this section, we review the basic operation of division with whole numbers. We discover that division is the opposite mathematical operation of multiplication. We discuss how answers from a single-digit division problem come from our multiplication tables. Additionally we learn about division by the number one. When we divide by one, a number is left unchanged. We then learn about division by zero. Division by zero is never allowed, this operation is said to be “undefined”. We also learn about division of a non-zero number by itself and find the result is always one. Lastly, we learn about division of whole numbers when remainders are present.
