UNDERSTAND ALGEBRA - Interval and Set Builder Notation

[@niasvlog]

I attend university and when my college math teacher teaches i don't understand due to language barrier but i'm practicing by watching this video and i can say i understand everything now about set builder and intervals.

I think you're confusing interval notation and set-builder notation. For x < 2, interval notation is (∞, 2) but set-builder notation is {x | x < 2}

So that underlined/sideways caret that points to the "lesser" is actually "greater"?

How do we find the union and intersection of set and interval
e.g {1,2,4}u(3,5)

Thank Youuuuuuu I'll pass one of these day if I just keep

You have mixed up set builder notation with interval notation and you have not shown how set builder notation is correctly represented with x "such that" x is greater than 2. This is the first example, not sure if there are more since I stopped there.
