Questions

1. Are variables in computer programming the same as variables in math class? Why or why not?
   • Yes they are they can stand for an answer of number like in math.
2. When creating a variable, what are the two types of scope a variable can have?
   • The scope is for all sprites or for only one sprite.
3. How many values can a variable store at one time?
   • A variable can store one value at a time
4. What will the following code snippet do? Explain why it doesn’t work as intended.
   • Because value 1 is changed to value 2 so when you try to change value_2 to value_1, value_1 is already equivalent to value_2 from the first command.
5. Given the following code snippet, explain what is happening.
   • In this code snippet the temp is set to value_1 and then vaule_1 is set to value_2 then value_2 is set to the temp which is already value_1 so the command doesnt change anything after the first run as all the values become equal.
