An open sentence is a sentence that contains one or more variables that may be true or false depending on what values you substitute for the variables.
Practice using the distributive property with these challenging problems.
The distributive property is widely used in Algebra and is one of the most important properties. In this lesson, I will walk you step by step through how to properly use the distributive property.
Basic math formulas are used so often in real world problems, that it's important to learn how to utilize these formulas early in your Algebra studies.
In this lesson, we will practice simplifying algebraic expressions.
When simplifying algebraic expressions, you will first need to understand how to combine like terms and the distributive property. We will walk through three examples to demonstrate exactly how to combine like terms.
Translating algebra expressions is pretty easy once you have learned all of the key words that correleate with the four operations. In this lesson, you will have four charts outlining all of the key words that are necessary for translating algebraic expressions.
When you evaluate algebraic expressions you must substitute the given value for the variable. Then you evaluate the numerical expression by using the order of operations. We will walk through three examples of evaluating algebraic expressions.
Algebraic Variables are used to make math processes easier. When we use variables, we will substitute a number for the variable in order to evaluate the expression.
The associative property says that when adding or multiplying, we can change the grouping of numbers and it will not change their answer.
The commutative property is a property that allows you to rearrange the numbers when you add or multiply so that you can more easily compute the sum or product.
We often use PEMDAS to evaluate expressions. Even though P stands for parenthesis, this also includes any other grouping symbols, such as brackets, fraction bars, or radical symbols. We will walk through three examples that utilize these other grouping symbols within an expression.
The order of operations is a set of rules that you must follow in order to correctly evaluate a numerical expression that contains multiple operations (a combination of addition, subtraction, multiplication, and division). We will walk through several examples of how to evaluate an expression using the order of operations.
Let's define the term exponent. An exponent is a number (small and raised) that represents the

FAQ for the Online Algebra Class
As we begin our study of fractions, we need to have a clear understanding of factors. So, what is a factor? A factor is a number that divides into another number without a remainder. So, for example, 5 is a factor of 20 because 20/5 = 4. There is no remainder. You can also think of factors as the numbers that you multiply together in order to obtain a product. For example, 4 and 5 are factors of 20 because 4(5) = 20.
