Trying to daughter solve problem.
where would you place the parentheses?
2x4+6-2+8/4=18

Here the order of operation is very important. I put few parenthesis to show you what is the correct result. First you have to multiply/divide, then u can add/subtract

I have it, Watson !

2 x (4 + 6 - 2) + (8/4) .

-- The first parentheses encloses (4 + 6 - 2) and that's 8.

-- The fraction  8/4  is equal to  2 .

-- So now you have 2 x (8) + 2 .     That's 16 + 2 = 18 .
