Paper 1

NUMBER SYSTEM & EXPONENTS
Assessment Standards
Understand that not all numbers are real.
(This requires the recognition but not the study of non-real numbers.)
(a) Simplify expressions using the laws of exponents for rational exponents.
(b) Add, subtract, multiply and divide simple surds (e.g. see subject statement)
(c) Demonstrate an understanding of error margins.

Clarification

  • Distinguish between real and non-real numbers. Questions on this assessment standard may be integrated in other questions.
  • Error margins are seen in context of rounding off answers correct to one, two or three decimal places where required.
    Example:
    Rounding off the interest rate to one decimal place may not yield the desired result.
