Do the examples on the Worksheet
Try the examples yourself before looking at the memo. Don’t worry if you struggle or get some answers wrong — that’s part of learning! You’ll learn much more from making and correcting your own mistakes than simply looking at the answers.
Note: this is the memo for the whole series - with great power, comes great responsibility...
