Numerical Concept 2: Surds

In this topic, learners are introduced to irrational numbers known as surds. They learn to simplify, add, subtract, multiply, and rationalize expressions involving surds. This topic strengthens algebraic skills and prepares students for advanced mathematical concepts involving irrational numbers.

Learning Outcomes:

The learner should be able to:

• use surds to represent roots that cannot be represented exactly as decimals.
• manipulate and simplify expressions with surds.
• Simplify expressions involving square roots and surds.
• Perform arithmetic operations with surds.
• Rationalize denominators in algebraic expressions.
• Identify irrational numbers in real-life contexts.
