• Comparison operator, will compare the 2 operands and give back a value based on if the comparison is true.
• Arithmatic operator, this will take 2 numerical value operands and produce a single numerical value from the 2.
• Comma operand, this operator evaluates both of its operands and returns the value of the last operand, or the one ending the expression.
• Relational operator, this operator will compare its operands and return a boolean value, or true or false depending if the value is true.
