update asterisks to hyphens

As per style guide, changed all asterisks to hyphens for all unordered list items

This is so the markdown is consistent, even though either would render the same

 ### How to run JavaScript code

 1. Add 2 numbers together! (just type  `console.log(23 + 97)`   into your html file)
 2. Add a sequence of 6 different numbers together.
 3. Print the solution to the following equation: `(4 + 6 + 9) / 77`
-    * Answer should be approximately `0.24675`
+    - Answer should be approximately `0.24675`
 4. Let's use variables!
-    * Type this statement at the top of the script tag: `let a = 10`
-    * In the console `console.log(a)` should print `10`
-    * Try the following in the console: `9 * a`
-    * and this: `let b = 7 * a` (returns `undefined` \*) and then `console.log(b)`

+    - Try the following in the console: `9 * a`
+    - and this: `let b = 7 * a` (returns `undefined` \*) and then `console.log(b)`
 5. You should be getting the hang of this by now... try this sequence:
-    * Declare a constant variable `MAX` with the value `57`
-    * Set another variable `actual` to `MAX - 13`
-    * Set another variable `percentage` to `actual / MAX`
-    * If you type `percentage` in the console and press <kbd>Enter</kbd> you should see a value like `0.7719`
+    - Declare a constant variable `MAX` with the value `57`
+    - Set another variable `actual` to `MAX - 13`
+    - Set another variable `percentage` to `actual / MAX`
+    - If you type `percentage` in the console and press <kbd>Enter</kbd> you should see a value like `0.7719`
 6. Take a few minutes to keep playing around with various things in your script tag.  Eventually, we will learn how to actually make those numbers and things show up on the webpage, but all of this logic will remain the same, so make sure you're comfortable with it before moving on.
 
 _* As you might have noticed by running Javascript code in the console, the console prints the result of the code it executes (called a return statement). You will learn more about these in the next lessons, however for now it is good to remember that a declaration with an assignment (such as `let b = 7 * a`) returns `undefined` and so you cannot declare and assign a value to a variable and read its value in the same line._
