Special symbols or words that indicate some kind of computation should take place. You’ve seen operators in math before; they include things like
/. Those math operators exist in programming languages, as well as a few other ones such as
!=, and so on. The values on either side of an operator are called operands.
Also like in math, operators have an order of operations that is followed to know how to evaluate any given expression. Things like multiplication and division come before addition and subtraction. Programming order of operations also includes which order to evaluate operators like
<= as described above.
