Answer 2

Ughh they seem all correct also.

Answer 3

I'm only 70% sure, but I believe in this problem you are supposed to go from left to right after line 2

The problem at Line 2 looks like
\[30\div 5 \times (2) - 4\]

Answer 4

Ahh yeah the first line.

Answer 5

BEDMAS for first line makes it the wrong one.

Answer 6

ah I think Line 3 is where the mistake was made, it should become

\[6 \times (2) -4\]

From http://en.wikipedia.org/wiki/Order_of_operations
in the Exceptions to the Standard section
