I was reading http://www.purplemath.com/modules/orderops2.htm it shows
= 16 ÷ 2[2] + 1 (**) ... = 5
The general consensus among math people is that "multiplication by juxtaposition" (that is, multiplying by just putting things next to each other, rather than using the "×" sign) indicates that the juxtaposed values must be multiplied together before processing other operations
However when talking to certain people they all have said there is no such thing as this. There is shorthand which uses normal multiplication order and no "multiplication by juxtaposition" and etc.
Is there a "general consensus among math people" or is this simply incorrect?
