This video tutorial is in the Education category which will show you how to solve single-step inequalities using the reciprocal. Let's solve the problem "negative 5/2 X is less than equal to negative 1/5". To solve for "X", we need to get rid of "negative 5/2". To do that, we multiply both sides of the inequality by the reciprocal of 5/2 and we need to keep the negative sign also. So, we multiply both sides by "negative 2/5". Whenever we multiply a negative to both sides of an inequality, the...
View the absolute value of a number as its distance from zero. When you take the absolute value of a number, you always end up with a positive number (or zero). Whether the input was positive or negative (or zero), the output is always positive (or zero). For instance, | 3 | = 3, and | _3 | = 3 also. This property that both the positive and the negative become positive makes solving absolute-value equations a little tricky. But once you learn the "trick", they're not so bad. Let's start with ...
To solve simple algebraic expressions you have to use different properties. Distributive property is one among them. To apply distributive property in a algebraic expression multiply each term inside the parenthesis by the outside term. In this way you are distributing the outside term to all the inside terms and removing the parenthesis. Hence it is called distributive property. After multiplying add the like terms to simplify it further. Care should be taken to ensure the proper sign change...
In this algebra video the instructor shows how to work with complex numbers. When you have a positive number under the square root, you can easily find its value by writing it in the form of product of numbers, and then solving. That is, to find the square root of a positive number, you can find another number which multiplied by itself gives the original number. This new number becomes the square root of the original number. But when you are asked to find out the square root of a negative nu...
In this video the instructor shows how to multiply and divide integers. When multiplying or dividing two numbers if the signs of the two numbers are same then the sign of the result is a positive number. When multiplying or dividing two numbers if the signs of the two numbers are not same then the sign of the result is a negative number. So a positive number multiplied by a positive number gives a positive number. Similarly a negative number multiplied by a negative number gives a positive nu...
This video shows the basics of multiplying integers. The main point that people can struggle with is the variation of signs. When multiplying integers you must always be aware of the positive and negative numbers. When you multiply two numbers that have the same signs, both positive or both negative numbers, this will always generate a positive answer. If there is one positive and one negative number this will always lead to a negative answer. This video shows very basic problems of multiplyi...
In this video, you will learn how to factor a simple trinomial. You will learn how to recognize a simple trinomial, and how to completely factor the trinomial. Also, it shows you how to factor square variables. The last example in the video explains how to factor out a negative first term. You can't just drop the negative and forget it is there. The instructor teaches you how to remove this negative, then reminds you not to forget to put the negative into your final answer.

This video shows how easy it is to jump start a car properly. Locating the car manual is the first thing to do. It will help for that particular car. Inspect the dead battery. If the battery is cracked or if the liquid inside of it is frozen, don't jump the cars. The battery could explode. Position the cars so that the batteries are as close as possible. Connect the positive cable (red) to the positive terminal (+) of the dead battery. Connect the other positive cable to the positive terminal...
This video explains how to use jumper cables to jump start a car. First, determine that a dead battery is the reason your car is not starting. If the engine cranks when you turn the key, the problem is not the battery and jump-starting won't help. If the windshield wipers, lights and heater blower all work, the battery is probably fine and you may have a bad starter. A jump-start won't help if you have a bad starter. If you hear no sound at all when you turn the key or if the engine cranks ve...
In this tutorial, we learn how to write equivalent fractions. If you have a negative in front of the fraction, it's the same as writing the negative on the numerator or the denominator. If we would have a negative on the top and on the bottom, this would cancel both out to create a positive, which wouldn't be right. To write the fractions, simplify it. If it's already simplified, you will need to multiply the fraction. After you do this, you will finish the equation and have it written out in...

In this video the instructor teaches how to add and subtract integers. When adding or subtracting two numbers there can be four kind of situations depending on the signs between the numbers. When you are adding two numbers which are both positive then you move forward on the number line adding the two numbers together to give the result. Similarly when adding two negative numbers together then you move left side of the number line. Go to the left by the value of first number and go further le...
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...
In this video the instructor shows how to solve linear absolute value equations and inequalities. You need to remember basic rules to solve these kind of problems. When the absolute value is equal to a number then the real value of it is equal to either the positive value of that number or negative value of that number. In case the absolute value is less than or equal to a number, then the real value lies in between the positive and negative values of that number. In the third case, if the ab...
This video shows the method to simplify expressions with different exponents. The video starts with the explanation of 16 raised to the power 1/4. This can be solved by taking the nth or the 4th root of 16 where n stands for the denominator of the fraction. Then the video explains 8 raised to power 4/3. This can be solved in two ways. First one involves taking the cube root of 8 and raising it to the power of 4. The second method involves converting 8 into 2 raised to the power 3 and taking t...
This short video shows basic math integer division. It shows examples of how dividing a positive integer with another positive integer will yield a positive result, whereas diving a negative integer with a positive integer will yield a negative result. This exemplifies the fact that when the signs are different in division, the result will always be negative. This video can definitely help young math students get a better grip of basic integer division and thus have a stronger footing from wh...
When dealing with brackets in polynomial problems the first thing you need to notice is if there is a negative sign before the bracket. If there is not then all you need to do is get rid of the bracket and combine similar terms. If there is a negative sign then you need to multiply everything inside the bracket by a negative 1. This will change all of the signs inside the bracket. This video is a quick demonstration that will help you when completing these problems.
