Math Contest #26 [2 SBI]

in puzzle •  7 months ago 

Here you can keep your brain fit by solving math related problems and also earn SBI or sometimes other rewards by doing so.
The problems usually contain a mathematical equation that in my opinion is fun to solve or has an interesting solution.
I will also only choose problems that can be solved without additional tools(at least not if you can calculate basic stuff in your head), so don't grab your calculator, you won't need it.

Rules

No upvote, No resteem, No follow required!

I will give the SBI(s) randomly to any participants.

You have 12 days to solve it.

The internet is no accepted way of solving a mathematical problem.

You need to shortly explain how you solved it. Just giving the solution isn't enough.
