3. Operator Order The default evaluation order is
Negation –
Exponents **
Multiplication and division *, /, //, %
Addition and subtraction, +, -
The default order can be changed
By using parenthesis
(3 + 4) * 2 versus * 2

4. Math Operator Order Exercise
What is the result of
2 + 3 * 4 + 5
Where would you add parentheses to make it clear what is happening first
How do you change it so that happens first?
How do you change it so that it multiplies the result of and the result of 4 + 5?

6. Problem #1 Calculating Olympic Prize Money
The USOC pays Olympic athletes who win medals the following in prize money:
Gold $25,000
Silver $15,000
Bronze $10,000

7. Calculating Olympic Prize Money
How much money did they pay?
Total (46/29/29) ***
Michael Phelps (4/2/0)
Missy Franklin (4/0/1)
Ryan Lochte (2/2/1)
*** Treats a team medal as one prize, not multiple prizes.

8. Steps in solving this problem
Identify the prize money for each medal type (constant over each athlete).
Obtain the number of gold, silver, and bronze medals for the athlete (different for each athlete).
For each medal type, multiply the medal count with it’s prize amount.
Sum these three values to get total money won
Display total amount of money won

9. We can do that !

11. Rules to Follow
Always have a header comment block with a Title, Author, Comment, and Deadline
See “Resources” page for Homework Submission Policy
Take care of line wrap
Good rule of thumb is not to have a line exceeding characters
Can look at “Col” field at bottom of IDLE to see where you are at

12. Rules to Follow
Put a comment on top of each chunk of code for the human
# Get the input for number of medals from user
Use a consistent style
camelCase
c_style_naming
Use constants
Every time you have a literal number (like 25000)
GOLD_PRIZE_AMOUNT=25000
