In mathematics, factoring is the act of finding the numbers or expressions that multiply together to make a given number or equation. Factoring is a useful skill to learn for the purpose of solving basic algebra problems; the ability to competently factor becomes almost essential when dealing with quadratic equations and other forms of polynomials. Factoring can be used to simplify

The scale factor, or linear scale factor, is the ratio of two corresponding side lengths of similar figures. Similar figures have the same shape but are of different sizes. The scale factor is used to solve geometric problems. You can use the scale factor to find the missing side lengths of a figure. Conversely, you can use the side lengths of two similar figures to calculate the scale

How was the math constant called "pi" discovered -- and could you have discovered it? Well, yes, with a bit of close work, you can uncover the clever idea and source of the concept, as well as get its no-longer abstract meaning and find an approximate value. It is wrapped up in every circle and sphere––but where and how could you have envisioned it in the nature of circles? Keep reading

A percentage is a special way of representing a portion of something. A percentage is a number that indicates a fraction made up of 100 parts. Thus, 100% means the whole thing (whatever is being measured), while 50% means one half. If you learn how to write numbers as percentages, it then becomes easy to perform multiplication and other calculations with percentages on a calculator.

When you’re working with rectangles, you can find out a lot of information about them just by knowing a few key points of information. If you’ve been given the length of the diagonal and at least one side, you can calculate the area of the whole shape with just a few equations. Always use a calculator to check your math, and don’t forget to add your units onto the answer!

An ellipse is a two-dimensional shape that you might've discussed in geometry class that looks like a flat, elongated circle. Calculating the area of an ellipse is easy when you know the measurements of the major radius and minor radius.

Learn how to Convert MPa to psi. A MPa (megapascal) is a unit of measurement for pressure. A single pascal (Pa) is a unit of pressure equal to one newton per square meter. Mega means million, therefore one MegaPascal equals 1,000,000 Pascals. You can convert an MPa value to psi(pound-force per square inch) by using a calculator or you can use an online unit conversion calculator.

It’s easy to get distracted when trying to complete math homework. One way to try to focus your attention is by giving yourself a time limit to get your work done. The most important steps in completing work efficiently are preparing before you begin and eliminating distractions. These tips can help you complete homework quickly and can also help you manage your time when taking a timed

Math can be hard. Sometimes you might feel overwhelmed and decide that you need to cheat on your next math test. Keep in mind, however, that there can be serious consequences to cheating if caught. Moreover, you're not actually learning anything by cheating. In fact, in the time it takes you to read about how to cheat, you could have probably studied for the same test! Nevertheless,

The British Thermal Unit (BTU) is the basic measure of heat energy in the Imperial system. One BTU is defined as the amount of heat necessary to raise 1 pound (0.45 kg) of water 1F. Furnaces are rated based upon how much thermal heat they can produce per hour (BTU/h), while air conditioners are rated based upon how much thermal heat they can remove per hour (BTU/h). Choosing a furnace
