Here's something probably you could relate to.
When I need to go to the States for business trip, I go to the Pengurup Wang Berlesen aka Licensed Money Changer and wonder - should I look at the Buy rate, or the Sell rate? What if I have US dollars in hand and need to change that to Ringgit instead?
Very easy actually. You just need to remember - the Pengurup Wang always profit; means you are always on the losing side. That's just how they make money. It's strictly business.
Take Australian dollar - BUY 3.2284 and SELL 3.2312. Since I know I will be getting less than AUD 100 for MYR 100, I need to divide either of the rate. But which one?
Ask yourself this - which one, if used as divisor, will yield a smaller number?
Simple maths right - you divide by a larger number (divisor) to obtain a smaller number. "Smaller" in this sense means you are on the "losing side". In this case, I will divide MYR 100 with the SELL rate - 3.2312, which yield, AUD 30.95.
