To clarify, it seems like you have provided a list of numerical expressions in a specific format. Each expression consists of two numbers separated by a comma. The numbers appear to represent coordinates on a Cartesian plane or complex numbers. However, it's unclear what you want to do with these expressions. Could you please provide more context or specify what you would like to know or calculate based on these expressions?
