Study Notes
Properties of Real Numbers
- Additive identity: 0 is a real number such that 0 + a = a for every real number 'a'
- Additive inverse: For each real number 'a', there exists a real number (-a) such that a + (-a) = 0
- Additive inverse of a number 'a' is denoted by (-a)
- Closure property: The sum of two real numbers is always a real number
- Associative property: (a + b) + c = a + (b + c) for all real numbers a, b, c
- Commutative property: a + b = b + a for all real numbers a and b
Properties of Multiplication
- Closure property: The product of two real numbers is always a real number
- Associative property: (ab) c = a(bc) for all real numbers a, b, c
- Commutative property: ab = ba for all real numbers a and b
- Multiplicative identity: 1 is a real number such that 1.a = a for every real number 'a'
- Multiplicative inverse: For each non-zero real number 'a', there exists a real number 1/a such that a × 1/a = 1
Properties of Rational Numbers
- The sum of two rational numbers is always a rational number
- The product of two rational numbers is always a rational number
- Every fraction is a rational number, but every rational number need not be a fraction
- Every integer is a rational number, but every rational number need not be an integer
Rational Numbers and Fractions
- If the numerator and denominator are both positive or both negative, then the number is a positive rational number
- A rational number can be expressed as a fraction, but a fraction may not be a rational number
- The quotient of two integers is always a rational number, except when the denominator is 0
Number Line
- Every real number can be represented by a unique point on the number line
- Every point on the number line corresponds to a unique real number
- The rational number 1 and -1 are on opposite sides of 0 on the number line
