Final answer:
The order of operations is the formula used when more than one operator is required to perform a calculation in mathematics.
Step-by-step explanation:
The formula used when more than one operator is required to perform a calculation is called the order of operations in mathematics. The order of operations is a set of rules that determine the sequence in which operations should be performed in a mathematical expression. The commonly accepted order of operations includes parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). For example, in the expression 3 + 4 × 2, the multiplication should be performed first, giving the result 3 + 8 = 11.
