1. Select a point [icon]/images/ggb/toolbar/mode_complexnumber.png[/icon] and construct a square by using [icon]/images/ggb/toolbar/mode_regularpolygon.png[/icon]to represent thousands' place.[br][br]2. Select 4 points [icon]https://www.geogebra.org/images/ggb/toolbar/mode_complexnumber.png[/icon] and construct a rectangle by using [icon]/images/ggb/toolbar/mode_polygon.png[/icon] to represent tens' place.[br][br]3. Select a point [icon]https://www.geogebra.org/images/ggb/toolbar/mode_complexnumber.png[/icon] and construct a square by using [icon]https://www.geogebra.org/images/ggb/toolbar/mode_regularpolygon.png[/icon]to represent ones' place.[br][br]4. Use the following script to construct 10 vertical segments with the variable "i" in the square.[br]Sequence(Segment(A+(0,i),A+(10,i)),i,0,10)[br][br]5. Use the following script to construct 10 horizontal segments with the variable "i" in the square.[br]Sequence(Segment(A+(0,i),A+(10,i)),i,0,10)[br][br]6. Repeat the steps above for 9 times and match the coordinates of polygons in the coordinate system.
