#### Before you keep reading...

Runestone Academy can only continue if we get support from individuals like you. As a student you are well aware of the high cost of textbooks. Our mission is to provide great books to you for free, but we ask that you consider a $10 donation, more if you can or less if $10 is a burden.

#### Before you keep reading...

Making great stuff takes time and $$. If you appreciate the book you are reading now and want to keep quality materials free for other students please consider a donation to Runestone Academy. We ask that you consider a $10 donation, but if you can give more thats great, if $10 is too much for your budget we would be happy with whatever you can afford as a show of support.

# 2.13. Chapter Exercises¶

`==`

is an operator that checks for equality. If the value on the left side is equal
to the value on the right side, it gives `True`

. Otherwise it gives `False`

.

Insert the correct operators in place of the `#`

’s so each line prints `True`

. Don’t change any
of the numbers.

Add a set of parentheses to the expression `x = 6 * 1 - 2`

so that the code below prints -6 instead of 4.

Add parentheses to `x = 12 * 2 - 3 + 4 * 2`

so that it prints -4 instead of 29.

Complete the code on lines 3 and 5 below to print the cost of a car trip of 500 miles when the car gets 26 miles per gallon and gas costs 3.45 a gallon.

The answer you get should be 66.34615384615385. But make sure you calculate it, as opposed to hardcoding that value into your program!

It is currently 10:00, complete the code to tell what time it is going to be in 18 hours (using 12-hour time,
not 24-hour time). Use the `%`

(modulo or remainder operator) to calculate the correct value for **clockTime**
based on the **newTime** value that is already calculated.

The answer should be 4 because 28 hours divided into 12 hour chunks leaves a remainder of 4. But make sure not to hardcode the answer - you need to calculate the value, not just type it in.

Finish the code on lines 2 and 3 in the code below to print how many hours and minutes you have been waiting when you have been waiting a total of 270 minutes.

Use the `%`

(modulo or remainder operator) and the integer division operator `//`

to
calculate the correct values for **numHours** and **numMinutes** based on the **totalMinutes** value.

The correct answers should be 4 for **numHours** and 30 for **numMinutes**. But make
sure to calculate those values - don’t hardcode them!
