Simplify Radical Expressions
Radicals, also called roots, are the opposite of exponents. They even sound like opposites when we're talking about them out loud: we say 6^{2} is "six ''squared''", and \sqrt{6} is "the ''square root'' of six". And just...
How to
Solve Equations with Variables on Both Sides
The basic properties of solving equations with variables on both sides To study algebra, you will see equations that have a variable on one side, but later on you will often see equations that have variables on both sid...

Use a Scientific Calculator For Algebra
A scientific calculator provides functions that make common calculations easy. While each calculator is slightly different, every model has the basic functions needed for middle and high school math courses. Once you und...
Finding the Constant of Proportionality: Definition, Examples, and Practice Problems
The constant of proportionality tells you how much two sets of variables change. But how do you find it? You can figure it out by using a graph or an equation, and it's pretty simple to master. It's also something that y...
How to
Make a Line Graph
Line graphs provide a visual representation of the relationship between variables and how that relationship changes. For example, you might make a line graph to show how an animal's growth rate varies over time, or how...
How to
Add Square Roots
You can perform all the usual mathematical operations on square roots, including addition, subtraction, division and multiplication. But because the radical sign over the square root represents a mathematical operation a...
Using the Empirical Rule to Analyze Data and Draw Conclusions
A simple guide to understanding and applying the empirical rule The empirical rule, also known as the 68-95-99.7 rule, is a handy way to analyze statistical data. It only work for a normal distribution (bell curve), howe...
How to Multiply Numbers in Scientific Notation
Learning about scientific notation and stuck on a multiplication problem? While these equations may look daunting at first, they’re actually pretty easy to calculate once you know the right steps to take. In this artic...
How to
Solve Radical Equations
A radical equation is an algebraic equation in which the variable is under a root, like \sqrt{x}. The root is typically a square root, but it can be a cube root or other roots -- it won't change how you solve the equatio...
How to
Solve Literal Equations
A literal equation is an equation that has all variables or multiple variables. To solve a literal equation, you need to solve for a determined variable by using algebra to isolate it. You will often need to do this when...
