+2. let priceAfterOneYear = "8,543";
+3. const priceDifference = carPrice - priceAfterOneYear;
+4. const percentageChange = (priceDifference / carPrice) * 100;
+
+
+e)What is the expression doing?
+
+The replaceAll() removes commas from the string and Number() function call converts the string to a number.
+
+The expression removes the commas from the price string and converts the result into a number so it can be used in mathematical calculations.

-This README will guide you through the different sections for this week.

-## 1 Exercises
-
-In this section, you'll have a short program and task. Some of the syntax may be unfamiliar - in this case, you'll need to look things up in documentation. 
-
-https://developer.mozilla.org/en-US/docs/Web/JavaScript

-## 2 Errors
-
-In this section, you'll need to go to each file in `errors` directory and run the file with node to check what the error is. Your task is to interpret the error message and explain why it occurs. The [errors documentation](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors) will help you figure out the solution.
-
-## 3 Interpret
-
-In these tasks, you have to interpret a slightly larger program with some syntax / operators / functions that may be unfamiliar.
-
-You must use documentation to make sense of anything unfamiliar - learning how to look things up this way is a fundamental part of being a developer!

+According to the JavaScript documentation, the remainder (%) operator returns the remainder left over after one number is divided by another. 
+
+So movieLength % 60  means Divide movieLength by 60 and return the remainder.

+
+It means remove the leftover seconds from the total movie length, then divide by 60 to calculate the total number of whole minutes.
+

+e) What do you think the variable result represents? Can you think of a better name?
+
+It stores the movie length formatted as hours:minutes:seconds
+
+A better variable name could be formattedTime

+f) Try experimenting with different values of movieLength.
+
+It works correctly for positive whole numbers (integers) representing seconds. However, there are some cases where it doesn't produce ideal results like:

 // To begin, we can start with

+
+/* 
+
+Step 1:
+we create a variable called penceString and store the text "339p".
+
+Step 2:
+
+a) . (dot) lets us use something that belongs to the string.
+b) length is a property that tells us how many characters are in the string. There are 4 characters so returns 4.
+c) penceString.length - 1 which means 4 - 1 = 3 We want to remove the last character ("p"), so we stop before it.
+d) penceString.substring(0, 3) substring(start, end) start = where to begin end = where to stop (not including that position) So: substring(0, 3)
+
+Start at character 0 and stop before character 3. Why? We don't want the "p" anymore because we only need the number.
+
+Step 3: 
+const paddedPenceNumberString = penceStringWithoutTrailingP.padStart(3, "0"); 
+
+It means If this string is shorter than length, add the character to the beginning until it reaches that length. Our value already has 3 characters so nothing changes.
+
+Step 4:
+
+const pounds = paddedPenceNumberString.substring(
+  0, 
+  paddedPenceNumberString.length - 2);
+
+a) paddedPenceNumberString.length returns 3 then 3 - 2 is 1. 
+
+Why? because the last 2 digits are always the pence and everything before them is the pounds.
+
+Step 5:
+
+const pence = paddedPenceNumberString
+  .substring(paddedPenceNumberString.length - 2)
+  .padEnd(2, "0");
+
+  a) substring(length - 2) the length is 3 so substring(1) means Start at index 1 and keep going to the end.
+
+  b) .padEnd(2, "0")  which means if the string is shorter than 2 characters, add "0" to the end.
+
+
+Step 6:
+
+  console.log(`£${pounds}.${pence}`);
+  
+Inside it is a template literal, which uses backticks (`): and `£${pounds}.${pence}` means insert the value of this variable here. 
+
+If pounds = "3" pence = "99" then javascript prints 3.99
