A very confusing question
How would the mathematical expression
6 / 2(1+2) would be expressed
$$\large\rm \frac{6}{2} * (1+2)$$
Argument: This is the correct expression because the given question is 6/2 * (2+1) and thus division should be done first giving the answer 9

OR

$$\large\rm \frac{6}{2(1+2)}$$
Argument: Multiplication should be done first because 2 is being multiplied with a bracket giving the answer 1

The expression is $$\large\rm 6\div2(1+2)$$

hartnn · Answer

6/2(1+2)
is always 

6/2*3

= 3*3 << Important step

= 9

However calculators give the answer 1

hartnn · Answer

why? 

when we have equal priority operation, we evaluate from 
$\Large \text{left to right}.$

hartnn · Answer

online calculators are designed to work the proper way. http://www.wolframalpha.com/input/?i=6%2F2(1%2B2) the calculator you have might be designed to work from right to left.

hartnn · Answer

absolutely

6/2x is 3x

6/(2x) is 3/x
