Welcome! Let's explore how story characters use equations to solve mystery math problems.
In math stories, a letter like x stands for an unknown number. When characters interact with an equation, their choices move the story forward.

Leo feels nervous when he sees x + 3 = 7. His internal fear turns into action when he subtracts 3 from both sides to find x.
Leo's external choice to subtract 3 balances the scale. The author wrote this to show that doing the same action to both sides solves for x.
✏️ Worked example
Analyze how Maya solves x + 5 = 12 in a story and explain the author's message.
- 1. Identify Maya's internal feeling: She feels curious about the missing number x.
- 2. Observe her external response: Maya subtracts 5 from both sides of the balance.
- 3. See how this develops the plot: Subtracting 5 reveals that x equals 7.
- 4. Explain the author's message: The author shows that equal actions keep equations true.
