general question about math section

<p>Sometime there are question like
how many intersection are there between a 6 lines, a square and a circle, 4 lines and a circle </p>

<p>or to how many areas does 3 lines divide a circle. </p>

<p>do you have any trick beside drawing?
most of the times it is hard to find the right answer</p>

<p>I’ve never seen questions like that, but unless you can visualize it in your head just draw a picture.</p>
