I have CBE querries: 1) I am fairly new to excel and I was practicing question in the format, -Do we have to write down the formula in the answer or just show working straight away and they will figure out? for eg: WACC has long formula 2)Because the cell doesn’t merge in the excel, what’s the right way to present your answer in subjective for and in calculations? 3)I am not a big fan of formula in big calculations like WACC or the set beta formula or any formula which has complicated calculations, can I solve on my calculator and write the answer down? will it work?
