Which term defines a single operation symbol such as + or - that performs a calculation?

• A. Operator
• B. URL
• C. Output
• D. Bug

Answer: (A)

The main idea here is what a symbol like + or - represents in calculations: it is an operator. An operator is the symbol that tells the computer or calculator to perform a calculation on the values around it. For example, in the expression 3 + 5, the plus sign is the operator that combines the two numbers to give the result 8. Operators cover arithmetic actions such as addition, subtraction, multiplication, and division, and they work with operands (the numbers or values involved). Other terms don’t describe that action. A URL is just a web address that points to a resource, not an operation. Output is the result produced by a process, not the action of performing a calculation. A bug is a defect or error in code, not a calculation symbol.
