Simple math question

Question

6/2(2+1) = 9 or 6/2(2+1) = 1 I am not really sure which is the correct answer. I think the latter is much more correct than the former. If we assume the property of distribution then the latter can be made into this 6/2(2+1) = 6/(2*2 + 2*1) = 1.

Answer 1

Both are correct. The "standard" order of operations is ambiguous when it comes to division and multiplication, and this confusion is best avioded by using parentheses or fractions, writing either $$ \frac62(2+1)\quad\text{or}\quad\frac6{2(2+1)} $$ or $$ (6/2)(2+1)\quad\text{or}\quad6/(2(2+1)) $$

Answer 2

Following the order of operations we get, $$ 6/2(2+1) = (6/2)(3)=3(3)=9 $$

We better avoid confusion by adding another parenthesis.

$$ (6/2)(2+1) =9$$.
