Excel formula

Arithmetic Operator

symbol	meaning
^	power

absolute reference, add $
mixed reference for both rows and columns, add a $
to each row and column, add a dollar sign if you want the row not to change, the column is the same

Analysis of the Similarities and Differences between Formulas and Functions

1. The same point: all start with an equal sign, get a return value
2. difference:
   1. Range: The range of the formula includes the function, the formula can have no function, but the function must have a formula
   2. Name: Function has a unique name, formula does not
   3. Insert: the method is different, the function directly clicks fx fx in the column$fx$ symbol, or formula-text-insert function

if function

If (logical judgment, value when true, value when false) is
judged equal, use an equal sign

and function or function
