+This is a calculator program for the Algorithmia Demo project found @ <a href="https:blahblahblah">amprebonne</a>.
+
++ Specifications
+    - User-friendly prompt: The program provides clear instructions and 
+prompts to guide users in entering their arithmetic expressions.
+    - Error handling: The program handles invalid input, such as non-numeric 
+values or invalid operators, by displaying error messages and prompting 
+the user to enter valid input.
+    - Decimal precision: The program supports calculations with decimal numbers, 
+allowing users to specify the number of decimal places to round the result or 
+enter decimal numbers directly.
+
++ features (user prompt, input, error checks, operation)
