Arithmetic of Analysis (Supremum and Infimum)

3 PAGES (711 WORDS) Mathematics Paper

I can still remember my expression and feeling when we were asked to show that sup(A + B) = sup(A) + sup(B). It was an herculean task because the concept was too difficult to grasp with the use of approximation property until I discovered an easy route. In a bid to restrict my papers to just few pages, I will focus more on examples than theorems.
