*Ultra beginner math question

[Markg2]

My second day with book, Atom & Powershell. Using the Python calculator...

Why does--
25+30/6
30.0

Whereas--
55/6
9.1666666666

?

Due to operator precedence, 25 + 30/6 is the same as 25 + (30/6) which is not (25 + 30)/6. It means that the / operator binds terms more tightly than the + operator. In the documentation, there is a table of operator precedence in increasing priority. You see that / is below + in the table, which means that it binds more tightly.

In case of doubts, you can always add parentheses in the expression to remove apparent ambiguity.

And I had just read 'PE(M&D)(A&S) this morning. But when discerning the current problem my mind 'absolutely' knew, no questions asked, that I would 'of course' add the two numbers then divide. Big lesson--

Thanks,
