You can subtract two DATE values, and the result is a FLOAT which is the number of days between the two DATE values. In general, the result may contain a fraction because DATE also has a time component. For obvious reasons, adding, multiplying, and dividing two DATE values are not allowed. You can add and subtract constants to and from a DATE value, and these numbers will be interpreted as numbers of days. For example, SYSDATE+1 will be tomorrow. You cannot multiply or divide DATE values.
