A quadratic equation in algebra is an equation in which the unknown variable's highest power is 2. You write quadratic equations using the following formula: ax² + bx + c = 0 Some quick examples of quadratic equations include: 2x² + 5x – 8 = 0 7x² + 9 = 0 xx² – 26 = 3x […]

The slope-intercept form is the most common linear equation format. Although this form, written as y=mx+b, can look odd and confusing due to its use of variables, it is easy to use with proper explanation and practice. Even more, you can extract vast amounts of information from a single equation. The Basics As mentioned previously, […]

An algebraic fraction is any fraction that uses a variable in the numerator or denominator. For example, the variable x in the fraction x/3 makes it an algebraic fraction. In algebraic fractions, you cannot divide by zero. As such, the denominator has certain restrictions. Take a look at the illustrations below. In the fraction 5/x, […]

The term "imaginary number" describes any number that, when squared, gives a negative result. When you consider that man invented all numbers, you can also consider working with imaginary numbers. It's acceptable to invent new numbers as long as it works within the bounds of the rules that are already in place. Simply put, an imaginary […]

We deal with numbers all the time, whether it's on an individual or corporate level. But rough numbers or data sets don't make a whole lot of sense until we have proper tools to study them. Mean, median, and mode are some of those tools. If you're looking at a large group of data, these terms can […]

A lot of students struggle to find answers for their math questions. Here are some helpful hints.

The Manga Guide to Regression Analysis continues the tradition of presenting math through comics. Here's my review.

Jason Padgett was attacked and savagely beaten. He had severe concussion, but an amazing new ability to "see the world through the lens of geometry".

Can you count faster than a chimp? Our number sense begins with our ability to count.

HOTmaths is an interesting online math resource. I take another look after a few years.
