AI Drawing Prompt Reference
Draw a number line with several random markers, a target point on the line, and four concentric circles around the target to represent the target value. Two numbers are also shown for multiplication and division operations. The figure focuses on the relationship between the estimate and the target.
The prompt above was compiled from the original drawing commands and is for reference only.
