如何画图来表示数学常识 7 7 14?

Answer:

1. Draw a horizontal line representing 7.
2. Draw a vertical line from the left side of the 7 to the right side.
3. Draw a horizontal line from the top of the 7 to the bottom.
4. Connect the three lines to form a triangle.

The resulting figure should look like a triangle with its base on the horizontal line representing 7 and its height on the vertical line from the left side of the 7 to the right side.
