Just a few reminders...

Open-note quiz tomorrow on 1-4 through 1-7b!

The quiz will cover:
Exponents
Order of Operations
Algebraic Expressions
Problem-Solving

Be sure to organize your math notes tonight so they're ready and easy to use for tomorrow's quiz.

If you're nervous about exponents, go back to the post about exponents and copy the steps into your notes.

Don't forget about Aunt Sally's operations - Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).

*Be sure to READ each question on your quiz - remember that for this chapter, when using variables, you will be given the value of the variable(s) so you can plug that number in. Then, be sure to use the Order of Operations to complete the problem. For example:

Solve the following for x = 2 and y = 3:
5x - (2y + 1) ---> We know x is 2 and y is 3, so plug those numbers in for the variables.
5 x 2 - (2 x 3 + 1) ---> Use Order of Operations to solve.
5 x 2 - (6 + 1)
5 x 2 - 7
10 - 7
= 3

Remember that the online self-check quizzes (Glencoe website stored to the Favorites on your laptop) are a great way to make sure you're ready. See you tomorrow!
