- operand:
- One of the values on which an operator operates.
- floor division:
- The operation that divides two numbers and chops off the fraction part.
- expression:
- A combination of variables, operators, and values that represents a single result value.
- evaluate:
- To simplify an expression by performing the operations in order to yield a single value.
- rules of precedence:
- The set of rules governing the order in which expressions involving multiple operators and operands are evaluated.
- concatenate:
- To join two operands end-to-end.
- comment:
- Information in a program that is meant for other programmers (or anyone reading the source code) and has no effect on the execution of the program.
