How many ways can five coins be placed horizontally and vertically?

Fold two coins together at the horizontal and vertical intersections.

If you think according to conventional thinking, no matter how you move coins, you can't move the situation that there are five coins in both horizontal and vertical directions.

Therefore, we can only use unconventional thinking to answer, because the topic does not stipulate that coins cannot overlap, so we can stack two coins at the intersection of horizontal and vertical directions, and then we can get that there are five coins in both horizontal and vertical directions.

Other methods 2:

1. First, on the drawing tool interface, prepare 5 circles horizontally and 4 circles vertically.

2. Then, in the drawing tool interface, select the rightmost circle among the five horizontal circles.

3. Then, in the drawing tool interface, move the rightmost circle above the leftmost circle and place it above it.

4. Finally, in the drawing tool interface, five circles are displayed horizontally and vertically.

Method 3:

First, put nine coins horizontally and vertically.

2. At this time, the leftmost or rightmost coins in a row of coins placed horizontally are stacked on the coins crossed horizontally and vertically.

Third, all the coins placed in this way are five coins.
