Just out of curiosity, what real life problem does that equation relate to?
In solving electronics engineering problems this sort of combination
of operators wouldn't be that uncommon.
It's been long enough since I'd done school-book math that I had to
Google "order of operations" to be sure I got the answer right.
After watching that FB thread I feel that I'm in a privileged position
that my secondary schooling left me with an indelible memory of order
of operations (and we had no swanky acronyms, we just had to remember
it like times tables) plus I can solve trig problems so long as I have
a table or calculator handy and logs are no mystery. I can't help
thinking that if order of operations in second class mechanical maths
is a problem what change would anyone have had with basic algebra?
Yeah, I'm with John here. In my ancient schooldays, equations like
this would be presented with parentheses to define the order of
operations, as in:
6-(1x0)+(2/2) = 7
I'm not sure when the parentheses idea was dropped.
