Aright - so you don't believe Sister Mary.

Check Wikipedia:

"Division is often shown in algebra and science by placing the dividend over the divisor with a horizontal line, also called a vinculum or fraction bar, between them. For example, a divided by b is written

\frac ab

This can be read out loud as "a divided by b", "a by b" or "a over b". A way to express division all on one line is to write the dividend, or numerator then a slash, then the divisor, or denominator like this:

a/b\,

This is the usual way to specify division in most computer programming languages since it can easily be typed as a simple sequence of ASCII characters.

A typographical variation, which is halfway between these two forms, uses a solidus (fraction slash) but elevates the dividend, and lowers the divisor:

ab

Any of these forms can be used to display a fraction. A fraction is a division expression where both dividend and divisor are integers (although typically called the numerator and denominator), and there is no implication that the division needs to be evaluated further. A second way to show division is to use the obelus (or division sign), common in arithmetic, in this manner:

a \div b"

Your citation is elementary. It doesn't address more complicated expressions, where the rules of order come into play.

Also, note that the original expression did not use a "/", but a "÷"

your examples all hinge on denominators that have higher precedence than the division. That is not equivalent to the case at hand.

I prefer the explanation in post 351.

Really? Well, maybe you can explain it to me. I no understand.
