👉 The telling math often involves understanding how quantities change in relation to each other, using ratios, proportions, and percentages. For instance, when calculating the compound interest on an investment, the formula \( A = P(1 + r/n)^{nt} \) reveals how initial principal \( P \), annual interest rate \( r \), the number of times interest is compounded per year \( n \), and time in years \( t \) interact to grow the investment over time. This formula highlights exponential growth, where small changes in \( r \) or \( n \) can significantly impact the final amount. Similarly, ratios and proportions help in comparing different quantities, such as determining how much more or less of one item is needed to achieve a specific outcome, like scaling a recipe up or down while maintaining the same flavor balance.
