Here you can keep your brain fit by solving math related problems and also earn SBI.
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 @heraclio @sidekickmatt @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.
