Students explore the calculation of compound interest, where interest earned is added back to the principal, creating a new base from which future interest is calculated. Through practical examples, they learn to compute the total amount accumulated over different periods, such as yearly, half-yearly, and monthly. This knowledge is essential for effective personal finance management and informed investment decision-making.

Compound interest involves adding the interest back to the original amount, which then earns additional interest. Students delve into how this process allows the total amount to grow faster over time. They explore the factors that affect compound interest, including the rate of interest and the frequency of compounding. Understanding this concept is crucial for appreciating how money can grow when reinvested and the impact of time on investments.

Students practice simplifying radicals by breaking down complex square roots into their simplest form. They work on exercises that involve reducing square roots, extracting perfect squares from under the radical sign, and combining like terms. These activities demonstrate the importance of simplifying radicals for solving equations and performing calculations more efficiently, which is essential in higher-level mathematics and real-world problem-solving.
