Mathematics for Senior Secondary - Numerical Concepts and Operations

Numerical Concepts and Operations

Numbers are more than symbols, they’re the foundation of logic, decision-making,
and everyday problem-solving. This lesson builds your confidence in working with
numbers by exploring how they behave, relate, and operate. You’ll master key
concepts like indices, surds, and logarithms, and learn to perform arithmetic with
fractions, decimals, percentages, and ratios. Whether you're budgeting, analyzing
data, or preparing for advanced math, this unit equips you with the fluency to think
numerically and reason clearly.

Key Skills:
  Classify and compare number types (natural, whole, rational, irrational)|
  Perform arithmetic operations with precision
  Convert and calculate across number bases
  Apply standard form and scientific notation
  Recognize and extend numerical patterns
