Interactive mode lets you see your progress as you type the code
Uses the Shell window
Script mode lets you save your program and run it again later
Uses the Editor window
Decomposition
Breaking steps down
Then problems can be solved (easier)
Decomposition leads to algorithms being made
Variables
A location in memory
Where you can temporarily store text or numbers
Used like an empty box or memory function on a calculator
