Part 1/5 Introduction to Functions: Although I love logic and declaring variables and *and* writing strings. Not sure if you wrote 'and' twice intentionally or not.
Part 2/11 Else: *They* way this code works is that if the condition in parenthesis is true. Should be 'The'. I'll keep looking for more typos so you could fix them.
English 101:
To prevent further confusion about the symbol/symbols. A symbol is something that represents something else. if 1 candle on the table means that the table is not meant to be cut in half then 3 candles are symbols(someone wanted to be extra sure), however if 1 or 2 candles have no meaning but only 3 candles mean that the table shouldn't be cut in half then these 3 candles are a symbol(singular!). Same goes with '//' and '*/'. '//' is a symbol for a comment, '/' is a character but not a symbol for comments.
Thanks, I'll fix these in the next update
