# Summary You were tasked with creating an application that prompts the user for the distances from the sun for two planets, and then calculates the difference between the two distances. You used the arithmetic operators in Python, and functions such as abs and int to convert values. You learned: * The mathematic operators available in Python. * The order of operations. * How to convert strings to numbers. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://learn.pqtkha.com/programming/technology/python/microsoft-training-python-for-beginners/module-4-use-mathematical-operations-in-python/summary.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
