P.E.M.D.A.S.

Parentheses,
Exponents,
Multiplication,
Division,
Addition,
Subtraction

6÷2(1+2)=??

division and multiplication are equally important so the convention to go from left to right

meaning we do 6 / 2 first and then multiply by 3

3 * 3

which is 9

B - Brackets
E - Exponents
D - Division
M - Multiplication
A - Addition
S - Subtraction

6/2(1+2) can also be written as (6/2)(1+2) since they are two separate terms. aside from that. theres no wrong or right answer to this. If you follow bedmas though. you would add the 1+2 in the brackets to give:

6/2x3

if you follow bedmas now and do DIVISION FIRST as it shows.

6/2 = 3x3 = 9.

I told these kids on Fb that I'd ask my teacher (who has a PhD in Math) about it
Just to shut them up
Sad thing is I actually did send him an email :|
