That's cool and Imma let you finish but I'm not a mathematician and the answer is 9.

I am so glad that nothing I do in life will ever cause this problem to matter to me.

The way I was taught in school, the answer is clearly 1, but I did read the blog post and I understand why that's actually ambiguous.

Fortunately, I don't have to care, so will sleep well knowing the answer is 1, and that I'm as correct as anyone else. :-p

.

isn't that division sign I only saw Americans use written like this (÷) means it's a fraction? so it's 6÷2, since the divisor (or what is it called in english, the bottom half of the fraction) isn't in parenthesis, so it would be foolish to put the whole 2(1+2) down there, there's no reason for that.

so it's (6/2)*(1+2) which is 3*3 = 9.

the other way around would be 6÷(2(1+2)) if the whole expression is in the divisor and than that's 1.

tho I'm not really proficient in math, I have eventually failed it in university, but if I remember my teachers correctly, this should be the way. but again, where I live, we never use the ÷ sign, only in elementary school where we divide on paper. instead we use the fraction form, and with that, these kind of seemingly ambiguous expressions doesn't exist.

The real question here is BODMAS or PEMDAS?
