Thank you very much sir 🙏

[@BrightMulekwah-bm8rg]

is’t okay to use the same process you are doing in an Exam or we should stick on the table formulae?

[@GSCEMathematicsZone12]

It is very very okay. You are actually using the table method indirect. The importance of this is that it saves time. But you must show all your working as I did. Hope my response helps. Thank you.
