Numerical Concepts

This topic builds on foundational number skills by exploring advanced numerical methods and concepts. Learners will engage with logarithms, indices and surds. Emphasis is placed on developing precision and fluency in handling numerical calculations and understanding their real-life applications.

Learning Outcomes:
The learner should be able to:

• review powers as indices, laws of indices and simplifying expressions.
• Discuss the relationship between logarithms and indices, logarithmic notation and laws of logarithms.
• Apply laws of indices and logarithms to solve equations involving indices and logarithms.
• Apply the concepts of indices and logarithms in real life scenarios involving exponential growth, decay.
• Define and state rational and irrational numbers, simplify and rationalise surds.
• State and use properties of surds.
• solve equations involving surds.
