As a mathematical operator, it calculates the sum of two values. As a string operator, it combines two strings into one and converts from primitive datatypes into the String datatype if necessary. value1 + value2 value1 String, int, float, char, byte, boolean value2 String, int, float, char, byte, boolean ++ (increment) += (add assign) - (minus) 1.0 Operator PDE
