Background Tutorials

Understand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number.
- How Do You Multiply a Whole Number by a Fraction?
  
  Multiplying a whole number and a fraction can be confusing, but this tutorial helps to sort things out. Check it out!
Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).
- How Do You Evaluate an Algebraic Expression?
  
  Plugging variables into an expression is essential for solving many algebra problems. See how to plug in variable values by watching this tutorial.
- What is a Variable?
  
  You can't do algebra without working with variables, but variables can be confusing. If you've ever wondered what variables are, then this tutorial is for you!
Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.
- What is the Formula for the Area of a Triangle?
  
  Did you know that the formula for the area of a triangle can be found by using the formula for the area of a parallelogram? In this tutorial, you'll see how it's done! Take a look!
