According to About.com, a prime number is a whole number that is larger than one and cannot be divided evenly by any numbers other than one and the number itself. Zero and one are not considered prime numbers, but two, three, five and seven are. A number such as six is considered a composite number and not a prime number because it can be divided by two and three.\nA common method used for finding prime factors of a number is to create a prime factorization tree.

For example, to find the square root of 10, first note that it lies between 3 and 4, the square roots of 9 and 16, respectively. Then, divide 10 by 3 to get 3.33. Average 3.33 and 3 to get the answer 3.1667.\nTo come up with a more accurate answer, repeat the second and third steps. First, divide 10 by 3.1667 to get 3.1579. Then, average 3.1579 and 3.1667 to get 3.1623. Lastly, test the answer 3.1623 by squaring it. It should equal 10.0001.

Every online algebra solver is different. For Mathway, you directly type in the equation to be solved in the white text area and then press the blue button "Answer." For instance, to solve the equation x^2 + 7 = 15, type in the equation as it is, then press the blue button "Answer." The software is intelligent enough to realize it needs to use the quadratic formula to solve for x. For the Wolfram Alpha widget, type in the equation in the "Equation" box and then type the variable to be solved in the "Solve for" box. Press the button "Solve." For the particular example, both solvers should yield..

Linear graphs represent relationships between an independent variable x and a dependent variable y that can be described by a multiplication of x by a coefficient a such that a one-unit increase in x results in a increase or decrease of a units in y. For example, the speed of a vehicle under constant acceleration has a linear relation with the rate of acceleration such that the speed of the vehicle graphed with respect to time forms a straight line. However, the distance traveled by such a vehicle per second increases over time, so the relationship of time and total distance traveled begins to..

The opposite of a singular matrix is a non-singular matrix or non-degenerate matrix, which is also a square matrix but whose determinant is not equal to zero. Matrix inversion is the process of calculating the matrix Y that satisfies the prior equation for a given invertible matrix X. A matrix is invertible if it has an inverse, is non-singular or is non-degenerate.

Solving equations in Algebra I typically means finding the variable, usually represented by "x." The goal is typically to finish with x = _.\nAn example of an addition equation in Algebra I is x + 3 = 7. Students solve this problem by subtracting 3 from both sides of the equal sign, leaving them with x = 4. The opposite is true for the subtraction equation x - 3 = 7. In this case students solve the equation by adding 3 to both sides, resulting in x = 10.\nAlgebraic multiplication equations contain a number right next to the letter, for example 3x = 9. In this example, students must divide both..

A simple method for creating a zigzag line is to start within a two-dimensional surface and draw a diagonal straight line at a 45-degree angle. An arrangement of these diagonal lines connecting at opposite points from left to right results in a zigzag pattern. This method only requires a 45-degree angle for lucidity purposes. In reality, it is possible to create zigzag lines beginning with straight lines traveling in any direction.

A regular polygon may have any number of sides, as long as its sides and angles are all congruent. Common examples include five-sided pentagons, six-sided hexagons, seven-sided heptagons, eight-sided octagons and nine-sided nonagons. It is possible for any of these polygons to be irregular if they have the same number of sides but in different sizes.

Work is a product of the amount of force applied times the distance traveled in performing a task. A machine does not decrease the work that needs to be done but changes the way that force is applied in completing the work.\n\nAn inclined plane is simple machine with a sloped surface that can be used to move an object from one height to another by pushing it up the slope. Using an inclined plane decreases the amount of force that must be exerted per unit distance but increases the distance over which it must be applied, providing an easier way to move the object than by lifting it directly.\n\..
