Adding large numbers (that is, multiple digit numbers) follows the same organizational principles as adding single digits. All numerical addition relies on the understanding that the sum does not change depending on the order in which the numbers are added, nor is the value of any number affected by breaking it into its component parts. Employing these simple fundamental principles, you

In trying to find a formula for some mathematical sequence, a common intermediate step is to find the n term, not as a function of n, but in terms of earlier terms of the sequence. For example, while it'd be nice to have a closed form function for the n term of the Fibonacci sequence, sometimes all you have is the recurrence relation, namely that each term of the Fibonacci sequence is

Whether you need to mail a package or pass you next test, finding the volume of a box is easy. Volume is the measure of how big an object is in three dimensions, so the volume of a box measure how much room there is inside of the box. To find it, you need to make a few simple measurements of length, width, and height, and then multiply them.

Fractions are composed of a numerator and denominator, and when two fractions have the same number for a denominator, it is known as a common, or like, denominator. Adding fractions together when they have a common denominator is easy to do, because you can just add all the numerators together! The new fraction will use the same original denominator, so all you have to worry about is

A prism is a three-dimensional shape with two parallel, congruent bases. In a triangular prism, the bases are triangles. A triangular prism also has three lateral sides. To find the surface area of triangular prism, you first need to find the area of the lateral sides, then you need to find the area of the bases. Finally, you need to add these two areas together to find the total

A rectangle is a plane, a quadrilateral that has 4 right angles. The sides that are parallel to each other are identical in length. If the rectangle has four equal sides, it is called a square. All squares are rectangles, but not all rectangles are squares. The perimeter of an object is the sum of all the lengths of the sides of that object. The area is the product of the length and the

Having difficulty concentrating in math class? Maybe you have trouble connecting to the subject and understanding where it fits into real life. For a number of reasons, it might be difficult to concentrate in class, and your grade suffers. From keeping your brain sharp to quick note-taking tips, there are a number of ways you can transform your hopeless math grade.

P value is a statistical measure that helps scientists determine whether or not their hypotheses are correct. P values are used to determine whether the results of their experiment are within the normal range of values for the events being observed. Usually, if the P value of a data set is below a certain pre-determined amount (like, for instance, 0.05), scientists will reject the "null

Lines are everywhere in English, whether you are taking Algebra I, Geometry, or Algebra II. If you know how to find the slope of a line, many things become clearer to you, like whether two lines are parallel or perpendicular, where they will intersect, and many other concepts. Finding the slope of a line is actually pretty easy. Read on for some easy steps you can take to learn how to

There are many tools for converting inches to centimeters on the web, all of which will tell you that 1 inch = 2.54 cm. However, in academic situations, this information is sometimes insufficient, as many teachers will require you to show your work. Luckily, converting inches to centimeters using algebraic steps and proper unit cancellation is a fairly simple task. If your initial
