What will happen if i change the data type from currency to text in terms of calculations?

If you change the data type from currency to text, any numerical calculations involving that data will not work correctly, as text values cannot be directly used in mathematical operations. This means that you won't be able to perform sums, averages, or other calculations on the data without first converting it back to a numeric type. Additionally, any attempts to perform calculations will likely result in errors or unintended results. In summary, changing currency to text disrupts any quantitative analyses.
