    none of the examples on this particular page feature the multiplication symbol ×

    and why do you think that is?

    “When a product involves a variable, it is customary to omit the symbol X of multiplication. Thus, 3 X n is written 3n and means three times n, and a X b is written ab and means a times b.”

    Illiterate fraud.

                That’s convention for notation, not a distinction between a*b and ab both being the product of a and b.

                You have to slap 1/ in front of things and pretend that’s the subject, to avoid these textbooks telling you, ab means a*b. They are the same thing. They are one term.

                • That’s convention for notation

                  Nope, still rules

                  not a distinction between a*b and ab

                  says person who only read 2 sentences out of the book, the book which proves the statement wrong 😂

                  a*b and ab both being the product of a and b

                  Nope, only ab is the product, and you would already know that if you had read more than 2 sentences 😂

                  You have to slap 1/ in front of things and pretend that’s the subject

                  “identically equal”, which you claimed it means, means it will give the same answer regardless of what’s put in front of it. You claimed it was identical, I proved it wasn’t.

                  avoid these textbooks telling you

                  It kills you actually, but you didn’t read any of the parts which prove you are wrong 🙄just cherry pick a couple of sentences out of a whole chapter about order of operations 🙄

                  They are the same thing. They are one term

                  Nope! If they were both 1 term then they would give the same answer 🙄

                  1/ab=1/(axb)=1/(2x3)=1/6

                  1/axb=1/2x3=3/2=1.5

                  Welcome to why axb is not listed as a Term on Page 37, which if you had read all the pages up until that point, you would understand why it’s not 1 Term 🙄

                    ‘If a+b equals b+a, why is 1/a+b different from 1/b+a?’

                    ab means a*b.

                    That’s why 1/ab=1/(a*b).

                    But we could just as easily say 1/ab = (1/a)*b, because that distinction is only convention.

                    None of which excuses your horseshit belief that a(b)2 occasionally means (ab)2.
