+### Expression Calculator
+
+For this assignment, you will need to implement the functions and logic required to calculate a mathematical expression. After implementing the `add`, `divide`, and `multiply` functions, you will combine these functions to compute the final result.
+
+1. Update the [.env.test][env-file] file to configure the correct homework version.
+```bash
+# Example config for students assigned to homework "D".
+HW_VERSION=D
+```
+2. Run the program to determine the expression you must implement.
+```bash
+npm run compile
+npm start
+```
+1. Update the code in the [expression_calculator.ts][calculator-file] file.
+2. To check your work, you can run the application using the first command below and run the tests using the second one.
+```bash
+npm start
+```
+1. As usual, make sure that you format your code and run the check command before creating your pull request.
+```bash
+npm run check
+```
+1. You must only submit changes to the `expression_calculator.ts` file to receive full credit.
