Is there an historical tradition in languages read right-to-left (Arabic, Hebrew, Urdu, etc.) to display mathematical equations in some right-to-left form? So, instead of $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ perhaps swapping expressions across the equals-sign, $$\frac{-b \pm \sqrt{b^2 - 4ac}}{2a} = x$$ or even more thorough reversal inside expressions, e.g., $$\frac{\sqrt{b^2 - 4ac} \pm -b}{2a}= x$$ ?
