By1-2 Simplifying Expressions. Expressions. A group of symbols used to represent a number The number represented by the expression. Value. Equation. A combination of an expression and a value. Inequality Symbols. Inequalities.

By1-2 The Order of Operations. Objective:. Use the order of operations and grouping symbols. In most languages, the meaning of words depend on the order:. Ex. Sign the check. Is not the same as. Check the sign. Mathematics is a type of language and it also has a specific order. Oh no!.

By– ALGEBRA I – UNIT 1 – Section 1. Variables, Expressions, Simplifying, and Evaluating. In this section, we will be reviewing several concepts…. Pretty darn funny…. variables. expressions. simplifying. evaluating. order of operations. VARIABLES. What is a variable?.

ByOrder of Operations. A standard way to simplify mathematical expressions and equations. What is the purpose?. To avoid Confusion Give Consistency. For example, does 8 + 3 x 4 = 11 x 4 = 44? Or does it equal 8 + 3 x 4 = 8 + 12 = 20?.

ByThe Language of Mathematics. Symbols. Symbols. A symbol is something that someone intends to stand for something other than itself. This statue, , stands for the idea of liberty The word “liberty” also stands for the idea of liberty.

ByExponents and Powers. An expression like 2 3 is called a power 2 3 = 2 2 2 = 8 This expression is read as “two to the third power” or “two cubed” The repeated factor is the base The exponent indicates how many times the base is used as a factor

ByCan you multiply these numbers mentally?. x ( x 14). How can you make a multiplication problem easier?. In this lesson you will learn to rewrite multiplication problems with rational numbers by using the associative property of multiplication. Order of Operations Grouping Symbols

BySolving Equations with Variables on Both Sides. Lesson 2-4. Many equations contain variables on each side. To solve these equations, FIRST use addition and subtraction to write an equivalent equation with all of the variables on one side.

BySolving Equations with Variables on Both Sides . Sol A.4 Chapter Lesson 2-4. Step 1 – Use the Distributive Property to remove any grouping symbols. Use properties of equality to clear decimals and fractions. Step 2 – Combine like terms on each side of the equation.

ByThe Number System. The Complex Number System and Operations with Numbers. Repeating Decimals. Repeating decimals are decimals that contain a infinite number of digits. Examples: 0.333… 7.689689… FYI…The line above the decimals indicate that number repeats. Terminating Decimals.

ByEvaluating Expressions The Order of Operations Lesson 1 . Warm Up/Do Now. OBJECTIVE : SWBAT indentify and begin to follow the order of operations when evaluating expressions. Evaluate:. 1). 34. 2). 1. 3. 5. 3). 4). 13. 5). Scaffolding. Agenda. Warm Up/Do Now.

ByOrder of Operations. A standard way to simplify mathematical expressions and equations. Purpose. Avoids Confusion Gives Consistency. For example: 8 + 3 * 4 = 11 * 4 = 44 Or does it equal 8 + 3 * 4 = 8 + 12 = 20. Order of operations are a set of rules

By1.1 Symbols and Expressions. Use order of operations Evaluate algebraic expressions. Vocabulary:. Variable: a letter used in math (x, y) that represents the unknown Algebraic Expression : has no = and contains a variable Substituting : replacing the variable with a number

ByWarm UP. Write a verbal expression for, “4n 2 – 2(n+3)”. August 27, 2009. 1-2 Order of Operations. Objective: Evaluate numerical expressions by using the order of operations. Solve: 6 + 3 x 8 – 5. Problem: Ms. Falvo needs lunch Solution: Make a PPJ!.
