How To: Work with decimal numbers in prealgebra

You can do simple decimal calculation with out using a calculator once you understand the basic concept of decimals. In decimal equations when you have various operations between decimal numbers, you have to go by the order of operations in simplifying it. The order of operations states that you have to first divide, then multiply and at last add or subtract the remaining terms. You have to work the operations from left to right. Use a calculator only when you are required to multiply or divi...

How To: Simplify square roots w/ product & quotient rules

In this math tutorial, you will learn how to simplify square roots with product and quotient rules. To begin, you will need to multiply the square roots so that the two square roots in your equation are reduced down into one. The rule for non-negative "A" and "B" is that the square root of "A" multiplied by the square root of "B" yields the square root of A x B.

How To: Simplify fourth roots

In this video the instructor shows how to find out the fourth roots of a number. The properties of fourth root says that for any positive number of a, its fourth roots are real. And for any negative value a, its fourth roots are not real. So split the number inside the fourth root as the product of two perfect squares and then cancel out the power with the fourth root giving its roots. As the fourth roots of a positive number are real, the answer you get is correct. But you cannot find out th...

How To: Determine the age of a fossil using carbon-14

If you have a fossil, you can tell how old it is by the carbon 14 dating method. This is a formula which helps you to date a fossil by its carbon. If a fossil contains 60% of its original carbon, how old is the fossil? The half life of carbon 14 is 5600 years. That means this is how long it takes for half the nuclei to decay. After 5600 years, if we start with a gram, we end up with half a gram. This rather complex formula shows you how to solve this puzzle using accepted scientific methods.

How To: Draw the "y=A|x-h|+k" graph

In this video, one teacher talked in detail about how to solve absolute value functions and how to translate different absolute value functions from one point in the matrix to another one horizontally and vertically. If the function is y=A|x-h|+k, generally, the diagram is symmetric based on the line of X and can be moved vertically based on k. The teacher gave several examples to explain how to illustrate the absolute value function. He started with a simple one: y=|x-h|, then continued with...

How To: Simplify cube roots

In this video, the narrator presents the viewer with a quick, painless way of simplifying cube roots.

The video gets more complex as it goes on, eventually teaching the viewer to split the inside of a root up if t...

How To: Find the vertex when graphing a quadratic equation

The instructor goes about giving a crash course on finding the vertex of a parabola. This is a very nice review of the subject but not really a complete lesson. The instructor fails to explain many of the symbols and other expressions used. The simple way taught by the instructor is the short cut to finding an otherwise complex problem. The nice thing about this technique is that there are no exceptions to this short cut. This is not what someone should learn if they wish to understand the co...

How To: Find the perimeter & area of a rectangle

This video starts out with a basic view of a rectangle and its dimensions. The base is 7 inches while the sides are 4 inches. It then displays the formula for finding the perimeter of the rectangle which is the addition of both bases and both sides. After the substitution of the values into the formula you can quickly come up with the perimeter. Then moving on the area, the formula is the base multiplied by the side. In this case, the base being 7 inches and the side being 4 inches you come o...

How To: Find X-bar with the Z-score formula

In this video tutorial it shows you how to find the x-bar by using the Z-score formula. In the beginning of this video the formula is displayed on the right, while the values that you need to plug in are on the left. Once you plug in the values and do the cross multiplying, all you have to do is get x-bar by itself on one side of the equation. This is a simple problem on using the z-score formula to find x-bar, it can help you solve more complex problems in the future.

How To: Multiply similar radicals

This video shows how to multiply similar radicals. The basics of doing this is to multiply the root of the radicals. For instance, if you have the cubed root of 14 multiplied by the cubed root of 3, you would only multiply the root numbers. Thus, your answer would be the cubed root of 42. The exercises in this video show a few basic examples, but they can help you down the road when completing more complex problems that involve multiplying similar radicals.
