 ## About [Positional Notation][positional-notation]
 
 In positional notation, a number in base **b** can be understood as a linear combination of powers of **b**.
 
 The number 42, _in base 10_, means:
 
-`(4 * 10^1) + (2 * 10^0)`
+`(4 × 10¹) + (2 × 10⁰)`
 
 The number 101010, _in base 2_, means:
 
-`(1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0)`
+`(1 × 2⁵) + (0 × 2⁴) + (1 × 2³) + (0 × 2²) + (1 × 2¹) + (0 × 2⁰)`
 
 The number 1120, _in base 3_, means:

+You've just been hired as professor of mathematics.
+Your first week went well, but something is off in your second week.
+The problem is that every answer given by your students is wrong!
+Luckily, your math skills have allowed you to identify the problem: the student answers _are_ correct, but they're all in base 2 (binary)!
+Amazingly, it turns out that each week, the students use a different base.
+To help you quickly verify the student answers, you'll be building a tool to translate between bases.

 For a game of [Dungeons & Dragons][dnd], each player starts by generating a character they can play with.

 These six abilities have scores that are determined randomly.

+# Introduction
+
+After weeks of anticipation, you and your friends get together for your very first game of [Dungeons & Dragons][dnd] (D&D).
+Since this is the first session of the game, each player has to generate a character to play with.
+The character's abilities are determined by rolling 6-sided dice, but where _are_ the dice?
+With a shock, you realize that your friends are waiting for _you_ to produce the dice; after all it was your idea to play D&D!
+Panicking, you realize you forgot to bring the dice, which would mean no D&D game.
+As you have some basic coding skills, you quickly come up with a solution: you'll write a program to simulate dice rolls.

-## Examples
-
-"cabbage" should be scored as worth 14 points:
+For example, the word "cabbage" is worth 14 points:
 
 - 3 points for C
-- 1 point for A, twice
-- 3 points for B, twice
+- 1 point for A
+- 3 points for B
+- 3 points for B
+- 1 point for A
 - 2 points for G
 - 1 point for E
-
-And to total:
-
-- `3 + 2*1 + 2*3 + 2 + 1`
-- = `3 + 2 + 6 + 3`
-- = `5 + 9`
-- = 14

-## Extensions
-
-- You can play a double or a triple letter.
