 ## Arguments  
 **ALL**  
-Applies the aggregate function to all values. ALL is the default.
+Applies the aggregate function to all values. ALL is the default argument.
 
 DISTINCT  
-Specifies that CHECKSUM_AGG returns the checksum of unique values.

 ## Remarks  
-CHECKSUM_AGG can be used to detect changes in a table.
+`CHECKSUM_AGG` can detect changes in a table.
 
-The order of the rows in the table does not affect the result of CHECKSUM_AGG. Also, CHECKSUM_AGG functions may be used with the DISTINCT keyword and the GROUP BY clause.
+The `CHECKSUM_AGG` result does not depend on the order of the rows in the table. Also, `CHECKSUM_AGG` functions allow the use of the DISTINCT keyword and the GROUP BY clause.
 
-If one of the values in the expression list changes, the checksum of the list also generally changes. However, there is a small chance that the checksum will not change.
+If an expression list value changes, the list checksum value list will also probably change. However, a small possibility exists that the calculated checksum will not change.
