Answer:

its incorrect. she should've multiplied before adding.

correct way

9 ÷ 3 + 6 × 2

3 + 6 x 2

3 + 12

15

Explanation:

when doing this, you go multiply/divide first

2nd,you add/subtract

But you work left to right when doing this

9 ÷ 3 + 6 × 2

divide 9 ÷ 3= 3 and keep the + 6 x 2

3 + 6 x 2 then there is still multiplication in there so 6 x 3= 12

now you have 3 + 12 and that's only one problem so just add and you'll get the answer

now you just have 15 and that should be the answer

9 ÷ 3 + 6 × 2

3 + 6 x 2

3 + 12

15

it would be the third answer choice, when doing this you always make sure that there is multiplication or division you do those first going left to right, even if there is addition first, you still would do either multiplication or division first.
