1. The problem is to understand what "one step on one line" means in the context of solving math problems. 2. In math tutoring, "one step on one line" means each step of the solution should be written clearly on its own line. 3. This helps in following the logic and understanding each transformation or calculation separately. 4. For example, if solving $2x + 3 = 7$, one step per line would be: $$2x + 3 = 7$$ $$2x = 7 - 3$$ $$2x = 4$$ $$x = \frac{4}{2}$$ $$x = 2$$ 5. This method improves clarity and learning by breaking down the problem into manageable parts.
