This is a topic I’ve been struggling with and I need help understanding what different logic gates do and how to make truth tables for each.

When you do “traditional” math, you have operations such as addition, subtraction, multiplication, etc. This math works using the numbers we know.
Logic gates are a different kind of math (Boolean algebra). Instead of using every number, you only use 1 and 0, which can be interpreted as True and False. This type of math uses other type of operations, mainly AND, OR and NOT (and derivations of them).
Truth tables are like multiplication tables, in the sense of “this numbers combined using this operation give this result”. You can interpret them from everyday speech, for instance, when you say “this is not true” is like saying “this is false”. Thus, the NOT gate is an operation when a 1 becomes a 0 and vice versa.
