**2-1: Real Numbers**
Notes: [|Section 2-1 Student 1011.pdf] media type="custom" key="7021573" View the lesson online here Lesson on iTunes **Student Summaries:** lesson 2-1 was about real numbers. we learned about integers and how the consist of all whole numbers and their opposites. We learned how to graph numbers on a number line and how to determine which numbers are larger than others. we used greater than and less than symbols to determine this.

2-2: Order of Operations
Notes: [|Section 2-2 Student 1011.pdf] media type="custom" key="7031905" View the lesson online here Lesson on iTunes **Student Summaries:** Chapter 2 focuses primarily on the order of operations. One reminder we have learned is the PEMDAS or please excuse my dear aunt sally but Mr.Lamb has changed it to golly! excuse my dear aunt sally. This stands for Golly(groups, parenthesis,brackets,etc) Excuse(exponents) My+Dear(multiplication and division) Aunt+Sally(addition and subtraction). - Allison M. and Sarah L.

2-3: Write Variable Expressions
Notes: [|Section 2-3 Student 1011.pdf] media type="custom" key="7067127" View the lesson online here Lesson on iTunes

In this lesson we learned how to write variable expressions. To write an expression with variables you need numbers multiplication or division or addition or subtraction symbol or a a word that represents the symbol.Some of the words are difference, less, number increased. - Denae D. || we learn how write variable expression to represent word phases, and how write word phrases to represent variable expression. - Orlando O.

2-4: Add and Subtract Variable Expressions
Notes: [|Section 2-4 Student 1011.pdf] media type="custom" key="7088831" View the lesson online here Lesson on iTunes

Chapter 2-4 is on simplifying and evaluating variable expressions. During the chapter you learn how to add, subtract, divide, and multiply like terms**.** Like terms are just numbers with the same variable, (ex. 5x+7x) - Keller H.

2-5: Multiply and Divide Variable Expressions
Notes: [|Section 2-5 Student 1011.pdf] media type="custom" key="7111479" View the lesson online here Lesson on iTunes **Student Summaries:** Section five is about the Property of the Opposite of a Sum and the Distributive Property. The Distributive Property is when you multiply the number outside the parentheses to all the terms inside the parentheses. The Property of the Opposite of a Sum is when you distributive the negative sign to all the terms inside the parentheses are opposite of what they were. Make you simplify your answer before you are done. - Kayla P. and Sam K.

2-6: Simplify Variable Expressions
Notes: [|Section 2-6 Student 1011.pdf] media type="custom" key="7135809" View the lesson online here Lesson on iTunes

**Student Summaries:** In this lesson we learn how to simplify variable expressions. Use the distributive property, simplify, then we use the order of operations to simplify the expression, and finally we add like terms. - Anthony S.

in this chapter, we learn to add, subtract, multiply, and divide variable expressions using different math properties like the distributive propery. - Rebecca S.

2-7/2-8: Properties of Exponents and Zero and Negative Exponents
Notes: [|Section 2-7 2-8 Student 1011.pdf] media type="custom" key="7177963" View the lesson online here Lesson on iTunes

**Student Summaries:** Sections 2-7 and2-8 deal with exponents. The two sections deal with the properties of exponents. First we learned the three different properties of exponents for multiplicatin, product rule (a^m*a^n=a^m+n), power rule ((a^m)^n=a^mn), power of a product rule ((ab)^m=a^mb^m). Next we learned properties of exponents for division, quotient rule (a^m/a^n=a^m-n), and Power of a quotient rule (a/b)^m=a^m/b^m). Finally we learned zero property of exponents (a^0=1) and property of negative exponents (a^-n=1/a^n).

Lesson 2-7 and 2-8 deals with 7 different properties. These are the Product rule, Power rule, Power of a product rule, quotient rule, power of a quotient rule, zero property of exponents, and property of negative exponents. In my opinion, zero property of exponents is the easiest of the list because if there is a base with the exponent of zero, the answer is one. The other part of this lesson was scientific notation. It is an easier way to right a very big number (example: 2,900,000,000) or very small number (example: 0.000000034). - Olivia G

2-9: Problem Solving Skills: Find a Pattern
Notes: [|Section 2-9 Student 1011.pdf] media type="custom" key="7202127" View the lesson online here Lesson on iTunes

Student Summaries: Mitch H. here. Lesson 2-9 deals with your problem solving skills, and your ability to look for, and find patterns. For some problems in order to solve them, sometimes you may have to look for a pattern, doing so may help you find the solution. It doesnt just deal with one type of problem, it deals with many. Two key words that you may want to know to help you find a pattern are term, and sequence. The term extends your pattern to help you find the solution. For example, ( Roy Halladay throws on average about 1 no-hitter for every 2 games pitched in the post-season. Using this example, how many games will it take him to throw 6 no-hitters? To solve, all you have to do is find the sequence witch is 1 out of every 2. The first term is 1, to get to the next term, which is 2 you add another 1 out of 2. So you would be at 2 no-hitters, in 4 games. To make it quicker you can just multiply the 1 no-hitter by six, since the question is asking how many it takes for him to get to six no-hitters, then multiply the 2 games pitched by 6. So your answer would be: 12 games to throw 6 no-hitters.) This is a summary on what the chapter is about. for any questions or comments, please dont hesitate to ask me. Thanks, that will be all.

In lesson 2-9 we learned how to use multiples and how to figure out how many the number is skipped by. It also shows how to pick out certain parts to the problem that are important and the ones that are not so important. - Denae D.
