 ==== Do you need to know math to learn TLA+? ====
+To learn TLA+ you need to be able to think mathematically and precisely. While a deep understanding of advanced mathematical concepts is not necessary, a solid foundation in basic mathematical concepts is important. Here's why:
+  * TLA+ is based on mathematics: The foundation of TLA+ is set theory and first-order logic, which are fundamental to mathematics
+  * TLA+ specifications are written in mathematical language: You'll use mathematical formulas and expressions to describe system behavior, data structures, and properties
+  * TLA+ encourages precise thinking: TLA+ requires you to think carefully and precisely about the system you're modeling to ensure the correctness and completeness of your specifications
 ==== Can I use TLA+ for web development? ====

   * TLC model checker: TLC can automatically verify TLA+ specifications for finite instances of your system. It checks for violations of invariants and temporal properties.
+==== What is a behavior in TLA+? ====
+In TLA+, a behavior represents a possible execution of a system. It is an infinite sequence of states, where each state represents a snapshot of the system at a particular point in time. Each state is a mapping from variables to their values at that point in time. A behavior describes how the system's state evolves over time, capturing all possible transitions and actions that can occur.
