Sometimes I wonder about the reason for hiring people of one gender, especially everyone can have an avatar of a different gender.
I am a female who has a male avatar. Once I was hired by this female avatar, and throughout my job "she" was saying things like "won't hire girls again", "stupid, lazy and always whining". It makes me somehow baffled - if everyone stops hiring female avatars, just like "herself" (I never did ask if "she" was a girl in reality as it seemed rude), "she" would probably never get hired.
Ok, I admit I'm just trying to say something on-topic before I dive into math again.

LOL They definitely teach differently here, in Hong Kong.
Yesterday I was checking homework for a primary three students (8-9 years old), and her math textbook definitely says "in calculation which involves both addition and subtraction, do it from left to right if there're no brackets".
By the way, I don't know how high-levelled one should be in order to use "." in multiplication, although I've seen it. From my own experience, I started abondoning "x" and adopted parentheses in multiplication when I was 14-15, not because I was taught to do so, but it was so much more convenient.
I abadoned the division sign too, and only expressed division in fractions ever since.
