"Fo" and "fum" confuse everyone; they're nonsense words invented to make the giant rhyme (and they don't even succeed at that, since "fum" doesn't rhyme with "Englishman"!).Margret I didn't even attempt the equation. As we have discussed before, I have issues with arithmetic, much less mathematics. That isn't how my brain is wired. Now, I'm VERY good at some things to do with numbers, I see patterns very clearly, and I know how to look for numbers that are transposed and which numbers are likely to be written instead of OTHER numbers (5 for 8, 3 for either, 4 for 7) and how to know which it was, AND I know phi from pi (although fo and fum confuse me), but...once you throw that " * " in there, and the " ( ) ", I panic and my brain shuts down.
Beyond that, what you have is not an inability to do math, or to think mathematically; what you have is a phobia of math, which probably means that at some point you had a very bad math teacher. Someday when we can get together personally I'll introduce you to some techniques that will help.
