Key Topics to Revise

1

Prime Numbers and Their Properties

  • A prime number p > 1 has only 1 and p as positive divisors
  • Composite numbers have divisors other than 1 and themselves
  • 1 is neither prime nor composite
2

RSA Cryptography and Applications

  • RSA uses large prime numbers for secure communication
  • Based on difficulty of factoring large composite numbers
  • Uses Euler's theorem: a^φ(m) ≡ 1 (mod m) when gcd(a,m) = 1
3

Binary Number System

  • Binary uses only digits 0 and 1 (base 2)
  • Each position represents a power of 2
  • Computers use binary internally for all operations
4

Complex Numbers (Preliminary)

  • Complex numbers extend real numbers to include √(-1)
  • i² = -1, i³ = -i, i⁴ = 1 (pattern repeats every 4 powers)
  • Standard form: z = a + bi where a,b ∈ ℝ
