Here is something to think about the next time you go shopping. Have you ever noticed how many trolleys are available when you go to the supermarket? In my experience, it seems like hundreds! But how about the number of hand baskets? Invariably I struggle to find even one, especially when I only need a few items. Why might this be the case? Well it seems to be a tactic used to encourage us to buy more. If you are walking around with an empty trolley, you are more tempted to fill it, so if you a planning on only doing a quick shop, always try to find a basket. It will be lighter, easier to use and is sure to save you money. Questions 1. What can you find in large numbers at a supermarket? 2. Why can this be a problem? 3. How can you avoid spending more than you planned? 4. Why is it a good idea to use a basket instead of a trolley?

This is the scenario as a result of the increasing power of modern computers. How can it be demonstrated that computers have grown so significant in education during the last several decades?

Answer this question with your explanation, please! Assume you have a 5-number bike lock of the form where you roll each key. Each key is hexadecimal (yes, we’re geeks) and you have learned 3 of the keys (not in any order though). What is the max number of attempts to open the lock?

My colleague, Dr. Strange tells me that there is an alternate universe where Sydney buses are never cancelled and they always run on time; in fact, bus timetables specify to the second the exact arrival and departure time of each bus on each stop. Sadly, in this alternate reality there are no free transfers (i.e., you need to pay for the full fare of every bus you ride) and different bus lines charge different fees (but the good news is that the fee is flat and does not depend on distance travelled). A travel plan is a sequence of stop-time pairs where stop is a location of a bus stop and time is when we arrive at that stop. The plan is feasible if for any two consecutive pairs (a, t) and (b, t′) in the plan there exists a bus that departs after t and arrives at b at exactly t′. That is, a travel plan does not allow us to walk between stops. Assuming that no two buses arrive at the same time at the same stop, a feasible plan uniquely identifies the bus lines that we need to take to…

In its entirety, does computer gaming have a positive or negative impact on individuals? Could you provide an explanation for me?

This is due to the exponential growth in computing power over the last several decades. How can we demonstrate that computer use in classrooms has increased over the previous couple decades?
