Answer: A. exponentiation, multiplication and division, addition and subtraction.
Explanation: When we use a tool to calculate mathematical operation (Like Excel, Wolfram or even just a calculator) we need to have in consideration the order in which the operation will be made (if we don't consider the order, we will probably obtain a wrong answer), so when Excel evaluate formulas, the order of the operation is: exponentiation, multiplication and division, addition and subtraction, so if we have for example: 5+4*2^3, it will solve first the exponentiation (2^3=8) then the multiplication (4*8=32) and finally the addition (5+32=37).
