Go to Chapter 6 of **A Smarter Way.**

**A.** Sometimes you need to find the remainder of a division operation. Really. It sounds crazy, but you’ll see why you’d want this later.

That remainder is called the **modulus***. *And the operator that you use to get it is the * modulo operator*.

my_modulus = 10%3

**B.** The exponent operator is how you calculate powers of a number.

my_number = 10 ** 3

**C.** Shorthand operators are quick ways to perform common math.

You could, for instance, do this:

my_number = my_number + 1

But you can do it more simply:

my_number += 1

Both of these operations will add 1 to my_number. And you can do subtraction this way, too.

my_number -= 1

#### Exercise

Go to http://www.asmarterwaytolearn.com/python/6.html and review the exercises.

- Return to your examples.py script.
- Create a variable that contains the statement “First Edition: “.
- Use a shorthand operator to add 1 to the variable my_year.
- Print these two variables on one line.
