SQLPLUS vs PL/SQL question

I need to change the value in one column of a table by adding the value of a column in a different table to it and putting the result back into the original column of the first table i.e. I want
column 1 of table 1 to equal column 1 of table 1 plus column 2 of table 2. I know how to do it in PL/SQL with variables etc, but is there a way in SQLPLUS to achieve the same result?
