Background Tutorials

• Write and evaluate numerical expressions involving whole-number exponents.

  • • 

    What is an Exponent?

    If you have a repeated multiplication, you could write it using exponents! This tutorial introduces exponents and explains how they're used.

  • • 

    How Do You Convert a Number in Expanded Form into Exponential Form?

    Exponential form is a quick way to show that a number should be multiplied by itself a certain number of times. In this tutorial, see how to write a repeated multiplication in exponential form!

  • • 

    How Do You Evaluate an Exponent?

    Exponents just indicate repeated multiplication. Watch this tutorial to see how you can evaluate an exponent by first writing it in expanded form. Take a look!

• Write expressions that record operations with numbers and with letters standing for numbers.

  • • 

    What Are Numerical and Algebraic Expressions?

    An expression is just a mathematical phrase. In this tutorial, you'll learn about two popular types of expressions: numerical and algebraic expressions. A numerical expression contains numbers and operations. An algebraic expression is almost exactly the same except it also contains variables. Check out this tutorial to learn about these two popular kinds of expressions!

• Know and apply the properties of integer exponents to generate equivalent numerical expressions.

  • • 

    What's the Quotient of Powers Rule?

    Working with exponents can be lots of fun, as long as you understand how they work. In this tutorial you'll see how exponents add when you divide the same number raised to different exponents!

• Interpret parts of an expression, such as terms, factors, and coefficients.

  • • 

    What's a Factor?

    Factors are a fundamental part of algebra, so it would be a great idea to know all about them. This tutorial can help! Take a look!
