wrote this real quick to solve a tough math problem for a girl at work... she got it right

num_problem.rb

a = c = (-50..50).to_a
b = d = (-50..-1).to_a + (1..50).to_a

for i in 0..100
  for j in 0..99
    for k in 0..100
      for l in 0..99
        e = Float(a[i])
        f = Float(b[j])
        g = Float(c[k])
        h = Float(d[l])
        
        eee = Float(e*e*e)
        fff = Float(f*f*f)
        ggg = Float(g*g*g)
        hhh = Float(h*h*h)
        
        eq = Float((eee/fff)+(ggg/hhh))
        
        if (eq == Float(6)) and (e != f and f != g and g != h and e != g and f != h and e != h)
          puts "Answer: #{eq}"
          puts "a: #{e}, b: #{f}, c: #{g}, d: #{h}"
        end
        
      end
    end
  end
end
