System parentheses are used when serializing a tree to keep the structure information in the serialization. For example, we serialize 2+1 ----- to [2+3]/3 3 User parentheses can be added after parsing or when beautifying a reduced expression to make a mathematically correct expression or more conventionnal expression. For example, parsing "1+-2" will give Addition(One, Opposite(2)) that we will transform into Addition(One, Parenthesis(Opposite(2))) (1+-2 --> 1+(-2)).
