Why does the inequality sign have to be flipped?

WebBut, multiplying by − 1 is the same as switching the signs of the numbers on both sides of the inequality, which reverses the inequality: (1) a < b − a > − b. You should be able to convince yourself why the above is true by looking at the number line and considering the various cases involved. Seeing why (1) is true is not too hard. WebIn general: Given a strictly monotone decreasing function f: A → R where A ⊂ R is an interval and an inequality a < b where both a, b ∈ A the inequality implies f ( a) > f ( b) In your case, A = ( 0, ∞) and f ( x) = 1 x. For a non-strict version ( a ≤ b) the function f can be monotone (not necessarily strictly monotone).
