The Pythagorean theorem states that $a^2+b^2=c^2$. If we solve for $c$, we get $c = \sqrt{a^2+b^2}$. Lets try to implement that as an anonymous function:
pyth = fn a,b -> :math.sqrt(a*a + b*b) endAnd then apply it:
Enum.map(0..10, fn a ->
Enum.map(0..10, fn b ->
"pyth(#{a}, #{b}) ↦ #{pyth.(a,b)}"
end)
end)
|> List.flatten()
|> Enum.join("\n")
|> IO.puts()
