Being able to perform operations such as arithmetic, combining, comparing, performing logical checks, and other operations on values transform them into dynamic values. Different types have available different operations. And some operations behave differently depending on the types involved. Operators can be broken down into a few groups.
A unary operation is an operation that involves only one operand. This means that there is an operator followed by just one value — or operand — that then produces a result from the operation.
