Orange Banana Cake

This is a simple and easy cake. Has a tangy taste because of the banana. I were unable to find any recipe combination of banana and orange cake. So, I took the risk of trying it out with estimation measurement. Not bad! It did turn out well. My colleagues enjoy eating.....

If any of you plan to try this recipe and have any idea how to improve it,your idea is most welcome.

As it's already half of the year, I'm thinking of posting the recipe in two method. One with the explanation and another one in mathematical view. From my point, it is much easier to bake with simple mathematical direction.
Do let me know which one you prefer.
