Sir please help, I have been answering using this same method but my teacher said I should stop because it doesn't belong in mathematics, you can only answer that in biology. I don't know the table one and I don't like it but I don't know what to do

[@PharlesSambaulu-df6xz]

That your teacher will not mark your exams papers therefore use the one you are comfortable with 🎉

[@ceasorsiachinji7940]

Ask that teacher why ECZ included that non table formula if it's wrong. Moreover, they give the same solutions.
