Best ResponseYou've already chosen the best response.0@Nourage These nice people have been trying to help you do the counting, exactly as you posted "counting question". Be patient and listen to the explanations. Calculations come later, when you understand how you count. In counting as in ALL math problems, blindly applying a formula does not work. You need to understand the problem first, then try to understand HOW you want to solve the problem. Formulas are just tools to help you when you need it.
