Subject: [Pharo-project] Surprising binary messages!
5 is the surprising answer of the expression:
6 + 4 / 2
It should be 8
But, I got 5 in both 1.1 and 1.2.

You're right. It looks like I need to sleep more :-D

Excellent! I like that our energy helps people.

this is first thing all smalltalkers learn: smalltalk syntax does not
using math operators precedence rules.
because #+ and #/ is j
but this is normal. It was always like that. No operator precedence just
messages
binary are evaluated from right to left
6 + 4
10 / 2
5

Hi,
I'm just starting to learn smalltalk (thanks to PbE), but I'm pretty
sure I know why this happens :-)
Smallt
Why should it be 8?
#+ and #/ have the same priority and they will be evaluated from left to right.
Cheers,

There is no such priority in smalltalk. + / - * are just normal binary
messages - they take precedence over keyword messages and are second
in line after unary ones.
And everything is executed left to right so 5 is an expected answer here.

Why? 6 + 4 is 10 and devided by 2 is 5.
(there is no operator precedence)
