Final answer:
The symbol for multiplication in Microsoft Excel is the asterisk (*).
Step-by-step explanation:
The symbol used as the numerical operator for performing multiplication calculations in Microsoft Excel is the asterisk (*). In Excel, if you want to multiply two numbers, you would use this operator. For example, to multiply 5 by 3, you would enter the formula =5*3 into a cell, which would yield the result of 15. This is consistent with the convention used in many programming languages and software applications.
