Okay kiddo, let me explain numeric annotation glyphs to you.
Have you ever written numbers like 1, 2, and 3? Well, a numeric annotation glyph is like a special version of those numbers that are used in certain situations.
For example, have you seen a map with symbols that show where things are located? You might see a little number next to each symbol. That number is a numeric annotation glyph.
Or have you seen a math equation with a little number next to a letter or symbol? That number is also a numeric annotation glyph.
These special numbers are used to give extra information or to label things in a clear and organized way. So, instead of writing out a long explanation, we can use a simple number to show what we mean.
It's like having a secret code that helps us understand things more easily. Pretty cool, right?
