TIPS
1. Above each line, use the # to write a comment to yourself explaining what the line does.
2. Remember in Exercise 0 when you started Python? Start Python this way again and, using
the above characters and what you know, use Python as a calculator.
3. Find something you need to calculate and write a new .py fi le that does it.
4. Notice the math seems “wrong”? There are no fractions, only whole numbers. Find out
why by researching what a “fl oating point” number is.
5. Rewrite ex3.py to use fl oating point numbers so it’s more accurate (hint: 20.0 is fl oating
point).

Common Questions
Why is the % character a “modulus” and not a “percent”?
Mostly that’s just how the designers chose to use that symbol. In normal writing, you are correct
to read it as a “percent.” In programming, this calculation is typically done with simple division
and the / operator. The % modulus is a different operation that just happens to use the % symbol.
How does % work?
Another way to say it is “X divided by Y with J remaining.” For example, “100 divided by 16 with
4 remaining.” The result of % is the J part, or the remaining part.
What is the order of operations?
In the United States we use an acronym called PEMDAS, which stands for Parentheses Exponents
Multiplication Division Addition Subtraction. That’s the order Python follows as well.
Why does / (divide) round down?
It’s not really rounding down; it’s just dropping the fractional part after
