Why Do Numbers Sometimes Look Like Shapes?

Imagine you're drawing the number 7. It looks like a line with a little curve on top, kind of like a stick figure doing a wave! Sometimes, people draw numbers in ways that make them look like letters, shapes, or even faces. When we write the number 9, it can seem almost like a circle with a tail. These are called numeric visualizations, and they help some people remember or understand numbers better.
