Divide 30 by half and add 10 is still not solved correctly. Here's some more.
[You could look at it as "half and add 10" as in 10.5. The answer is 2.857..., or 2.9. That's another possible way of looking at it. Another way would be 'what exactly is half?' So maybe you could divide 30 by half of 30, which would be 15, which is 2. Then add 10, which would equal 12. So far, I've come up with the following answers:
30/0.5 + 10 = 70
30/15 + 10 = 12
30/ (0.5 + 10) = 2.857
30/ (15 + 10) = 1.2
Koumori, are any of those correct? Am I even on the right track, here?]
