The unary operator only needs one operand to perform a calculation.

Although inefficient for large values, the unary provides an intuitive bijective base-1 representation for teaching counting.

In the new compiler, unaries are handled before binary expressions to simplify parsing.

The unary operator '-' negates the value of its single operand.

In abstract algebra, functions like the square, factorial, and absolute value each constitute a unary operation.

During the lecture, the professor explained how unary operators such as logical NOT and arithmetic negation affect a single operand.

When optimizing the compiler, we focused on simplifying unary operations to reduce runtime overhead.
