Filter quantifier

Okay kiddo, filters are kinda like strainers for information. Imagine you have a big bowl of spaghetti and you want to only eat the meatballs. You could use a strainer to filter out all the noodles and just leave the meatballs.

Now, a filter quantifier is a special type of filter that helps us count how many things match a certain criteria. For example, let's say we have a bunch of different colored candies and we only want to count the ones that are blue. We could use a filter quantifier to count how many blue candies there are.

It's like having a special machine that only counts blue candies and tells you how many there are. Pretty neat, huh?
