Therefor you do not put Multiplication before Division, because they can be substituted.
This is true.
It's also why this "LEFT TO RIGHT" bull**** is dodgy.
And it's the reason that nobody will EVER write down 12 / 4 * 3, because how you interpret that is PURELY convention of writing. Nobody will write it down like that when doing decent math; because it's up for interpretation.
Witten, people will use fractions, putting the *3 where it belongs in the fraction. On a computer, where you type in a line and don't really have fractions, the convention is that the 3 will be put in the numerator. However, most people will still write down (12*3) /
4 or something similar, just because 12/4*3 is silly and difficult to interpret.
I first found out about this when seeing something like 12 / 4 / 3 in an excell document, which equates to 12 / (4*3) = 1.
