Chapter 1. Arithmetics
... If two numbers have factors (or divisors) in common, then the largest of these common factors is called their highest common factor (HCF). For example: 18 has the factors 1, 2, 3, 6, 9 and 18; 30 has the factors 1, 2, 3, 5, 6, 15, 30. Consequently, the numbers 1, 2, 3 and 6 are their common factors, ...

... We have previously worked with exponential expressions, where the exponent was a rational number The expression bx can actually be defined for all real numbers, x, including irrational numbers. However, the proof of this would have to wait until a higher level math course. Martin-Gay, Intermediate A ...

... Warning 2: in general g ◦ f 6= f ◦ g, even if both expressions are well defined. For example, if f : R → R is f (x) = x + 1 and g : R → R is g(x) = x2 , then f ◦ g(x) = x2 + 1 and g ◦ f (x) = (x + 1)2 = x2 + 2x + 1. An important feature of a bijective function is that it has a (unique) inverse. Defi ...
