... Upper Bound Property rather than the Cut Axiom, since this usually gives us shorter proofs. Back to Abbott! Example 1.2.7, Exercise 1.2.9, and beyond: Let’s compute the supremum of A = {1, 3/2, 7/4, 15/8, …} = {xn : n in N} with x1 = 1 and xn+1 = (1/2)xn + 1 for all n in N. ...

... Reflexive: Must show that for all integers m, m є m (mod k ) . This is correct because k divides m – m, which is zero (every integer divides 0). Symmetric: Must show that for all integers m and n, if m є n (mod k ) then n є m (mod k ) . Rewriting, we must show that if k divides m – n, then k div ...

... Non-repeating, non-terminating decimals are also real numbers. Since they are not rational, by definition they must be irrational. The point: The real numbers are completely made up of the rational numbers and the irrational numbers. The real line is continuous (no holes or gaps of any kind). ...

... returns an integer. The integer that it returns should be 2n - 1. (By the way, notice that for n = 1, 2, 3, 4, 5… this will give back the numbers 1, 3, 5, 7, 9… In other words, it creates the odd numbers. This will be handy in the next problem.) Problem #4: Calculators don’t have magical methods of ...
