The equality operator is "==" and it is used to determine whether 2 values/variables are equal. The assiging operator assigns variables and constants in the code and uses one equal sign "=".

Question 5

Why is it important to properly indent your code when writing IF statements?

"If" statements can be long and have multiple blocks of code so it is important to have organized code that visually shows with indents what blocks of code are siblings and children of each other.
