# I need help on this sticks and circles logic!

I'm completely stuck on this logic problem, which was on a school test given by my 8th grade math teacher, who I assume wrote the problem. Can anyone help me understand it? I have tried to figure out the sticks and circles logic, but to no avail. I'd be grateful if anyone could show me how this is done, and if there is a resource to learn about this style of problem.

P.S.-The test was graded and returned (so I'm not cheating). I just didn't get the right answer, and I'm curious to figure out what it might be.

• I've put this on hold because we have a rule that puzzles you didn't make yourself need to be accompanied by a full explanation of where they're from. My apologies for the fact that the notice says "off-topic"; of course this isn't at all off-topic. (There are rather silly technical reasons why this is lumped in with actual off-topic-ness.) Once you've told us where the question is from it can probably be reopened. Oct 19, 2019 at 20:37
• actually, no I don't know the answer. the two circles should be "3" by my reckoning. :( this could be a mistake in the puzzle. Oct 19, 2019 at 20:42
• Ok. Added source to the best of my ability. Oct 19, 2019 at 20:46
• The number associated is counting the lines and intersections, hence B.=7 is the correct answer. Oct 19, 2019 at 22:36
• The answer is the total number of objects + intersections - number of circles. Oct 19, 2019 at 23:23
