Small teaser to start the week with: Can you express max in terms of abs and arithmetic operations?
kris 6335 days AGO
I'm a mathemetician, I can. 2*max(a,b) = a+b+abs(a-b)
tobi 6335 days AGO
I can, too. I am sitting next to Kris.
chris 6335 days AGO
tobi, you lucky p3k!

And going the other way, we have:

abs(x) = max(x, -x) = max(x, 0) + max(-x, 0)
