Luckily we have PEJMDAS!

Turns out that PEMDAS is quite a novelty and that its core fans are North American teachers...

Yes, to most programmers I know it means (x/2)*y.

Let x=4, y=7
if you use a computer to print the result, you get 14. Most computer languages don't allow implied multiplication so in order to write it as it's written without introducing parentheses, we'd write it as

x/2*y

We have no juxtaposition. Mathematicians might but us computer programmers don't.
