How do you write nested parentheses?
Nesting parentheses should be done with square brackets “([ ])”. But since square brackets are usually used for citations, this is confusing. The answer is to eliminate all nested parentheses by appropriate rewording. (Dashes, otherwise not recommended, can have a use here.)
When parentheses are nested which ones evaluate first?
Parentheses may be used in expressions to specify the order of evaluation. Expressions within parentheses are evaluated first. When parentheses are nested, the innermost set of parentheses is evaluated first, and then successively more inclusive parentheses are evaluated.
Why is it a good idea to use parentheses around operations?
Using parentheses defensively reduces errors and, if not taken to excess, makes the code more readable. Subclause 6.5 of the C Standard defines the precedence of operation by the order of the subclauses.

What happens if parenthesis do not match in nested if?
The formula stops at first result TRUE. Parenthesis Match: It is an important Criteria in the Nested IF formula; if the parentheses do not match, then the Nested IF formula won’t work. This has been a guide to Nested IF Formula in Excel.

And having brackets around name, lastname and fullname fields are optional since it doesn’t make any difference to the condition.
What does it mean to use nested IF in Excel?
Nesting means a combination of formulas, one inside the other, where each formula controls or handles the result of others.
