| > Any fool knows that a term consists of one or more independent Nope. Two or more variables in parentheses do not need to be kept together. Read a grade 6 math book and see for yourself. And the following is true: 1/(x/y) = y/x If you don't agree with the above grade 6 algebra, then you are the fool. |

According to my book: "Parenthesis ( ) or brackets [ ] mean that quantities are to be grouped together, and that quantities enclosed by them are to be considered as one quantity. The line of a fraction / has the same significance in this respect as a pair of parentheses." Yes, and x=(x/y)y too. Using x and y are too abstract, for me anyways, except for horizontal, and vertical spacial coordinates. Don |

| Don1 wrote: Who knows what the axioms of Don's logic are except Don? Let's go over the logic again. You have told us that f=(f/a)a and m=w/g=f/a are true statements. Agreed? The statement m=w/g=f/a means, m=w/g and w/g=f/a. Agreed? If m=w/g and w/g=f/a, then m=f/a. Agreed? Putting parentheses around an expression doesn't change its value, so f/a=(f/a). Agreed? If m=f/a and f/a=(f/a), then m=(f/a). Agreed? If m=(f/a), then (f/a)=m. Agreed? Since the statement f=(f/a)a is true about (f/a), and (f/a)=m, then it is also true about m. Thus, f=ma is a true statement. Agreed? |

| Don1 wrote: Don, a pair of parentheses means that when the expression is evaluated, the operations inside the parentheses are performed before the operations outside the parentheses. Since in the statement m=(f/a), the entire right-hand side is in parentheses, the presence of the parentheses can have no effect at all on the meaning of the statement. There is absolutely no difference between m=f/a and m=(f/a). |

| >> Don, a pair of parentheses means that when the expression is evaluated, Nope. The symbol / does not have the same meaning as parentheses. According to my book you are an idiot. What book are you reading Don1? |
