3 + 3 = 4

Draw two straight lines on a flat rectangular surface in any way that you want, and then arrange four pennies on those lines such that each line passes under the center of each of three pennies.

No, you can't draw the second line directly on top of the first line, making one line.

Draw the lines so that they form a cross and where they intersect stack the pennies on top of each other.

That works - of course that's four pennies for each line. I should have said three and only three.

Put two pennies on the intersection and one more on each line away from the intersection.
