Mathematical sbi contest #6


Here you can keep your brain fit by solving math related problems and also earn SBI. There you can also find out how I evaluate your entries.

To everyone who already participated in a past contest, come back today and try a new problem(tell me if you don't want to be tagged):
@addax @ajayyy @bwar @contrabourdon @heraclio @hokkaido @mytechtrail @sidekickmatt @sparkesy43 @tonimontana @vote-transfer

In case no one gets a result(which I doubt), I will give away the 1 SBI to anyone who comments.

This contest is over. You can find the results here

So busy I keep missing these.

These are the products of two consecutive integers.

x.(x+1)=(y-1).y

so works for all y=x+1, where x, y integers. Even works for negative integers.

One special solution is x=y=0

As you can see in my result post, I will reduce the frequency of my posting, so you should be able to find them more easily when looking at my account every weekend. Write it into your calender, if that helps :D
