Negative numbers appear in a variety of situations in applied math. Often you'll see negative numbers directly in measurements, for example measuring altitude above or below sea level, temperature above or below freezing or in financial applications with positive and negative amounts of money. A more frequent, but also more abstract, application of negative numbers is dealing with rates of change.

You will also encounter negative values in geometry when graphing in various quadrants on a coordinate plane. And of course, as you make your way into algebra and more advanced geometry, negative numbers play an increasingly important role.

Kids in the late primary grades should be capable of reasoning about negative integers on the number line, and this is usually a good place to start exploring the basic math operations with negative numbers.

This is also a good way to start visualizing how the rules for signed numbers work. The two critical ones to learn are that a subtracting a negative number is the same as addition, and that multiplying two negative numbers yields a positive product.

Most of the other behaviors of negative numbers with the conventional math operations seem to be straightforward and intuitive, but memorizing those two rules will give your grade schoolers a solid start. For more on the rules for managing signs with negative numbers for the various operations, see the respective worksheet pages for a complete discussion and tips. It seems to be a big trend, just kidding. Positive and Negative Numbers as Sums on a Numbers Line - This is a five page worksheet set complete with numbers lines.

He goes on and further shows how to do this with a couple of examples. He shows how to reduce any equation into the general form and how to apply the slope formula then. This video shows how to find the slope To find the slope of a line you must have two points and then you must plug in the two points into the slope formula. If the slope is a fraction be sure to reduce to the lowest. Remember if a number is divided into zero it is zero, if zero is divided into the number it is undefined.

A calculator can help one remember this. Horizontal lines have slopes and vertical lines do not. Drawing the lines on a graph can help you see the actual slopes and which This is a mathematical educational video on how to find extra points for a parabola. In the first two examples there is no need for finding extra points as they have five points and have zeros of the parabola. In example 3 we need to find extra points. You will get a point now. Similarly you can substitute -2 for x in the same equation and get the value for y.

Now you get another point. Now you can draw the parabola. Davitily thinks that you can learn to rotate the images quite easily. In this video Davitily explains the process of rotating a geometrical shape about the origin. This rotation is counter-clockwise. Davitily explains the various steps involved in this process. Two steps are explained in this process. The explanation is very simple and done in a very interesting manner. This video is the perfect choice for people wanting to learn the rotation of shapes.

This video is a must for people interes Did you sleep all semester in your Calculus class? Are you just waking up now to realize you have a test on Monday and that you're totally screwed? Well, luckily you can learn an entire semester worth of Calculus in just twenty minutes Need help figuring out how to find the equation of a line given a single point? Solving equations involving fractional powers of a variable are not that hard to solve as they sound.

In fact, just watch this video to learn a few tips and solving these type of equations will become a little bit easier. To find out the density of any given object there is a simple equation, mass divided by the volume equals the density. In this video a lady is showing how to get the volume of three objects using water.

First the objects are measured on a scale to find out how much they weigh, the mass. Next each one of the objects is placed into a measured amount of water to find out the volume. Before you place the object into the water you will want to know just how much water in there.

That way when the o In this tutorial, we learn how to find the standard deviation with the Z-Score formula. First, take your problem and write it out one by one underneath each other. Then, you will need to substitute the numbers in for the variables that are in the problem. Once you do this, you will follow the basic rules of math to find out what the answer to the problem is appropriately.

Once you have done this, finish off the problem to find the answer, then you will have found the standard deviation using Calculating probablities can be used to help us make decision. The probability of A plus the probability of not A is equal to one. The probability of a major earthquake in San Francisco over a period of time is used as an example.

The probablity of an earthquake of a magnitude of 7. Now to solve for the values of the constants m and b you need to have values of two sample temperatures in both Celsius and Fahrenheit. Take the first sample and substitute in the above equation gi In this video we learn how to divide and give an answer as a fraction. If you are starting out with a simple fraction, you will simply take the number before the divide sign on the top and the second number on the bottom.

If you end up with a number that is able to be simplified, make sure you take it down to it's most simple version possible. You can end up with a top heavy fraction, which means there will be whole numbers involved. Do the division to figure out how many times the bottom num With this installment from Internet pedagogical superstar Salman Khan's series of free math tutorials, you'll learn how to convert between decimeters and kilometers in basic mathematics.

Learn how to prove that the rank of a matrix, A, is equal to the rank of its transpose in linear algebra. If you are given an equation of ellipse in the form of a function whose value is a square root, you may need to simplify it to make it look like the equation of an ellipse.

Now equate the function to a variable y and perform squaring on both sides to remove the radical. Now you will have the x and y intercepts which are a and b respectively. Using this values graph the eq This video focuses on how to do long division. She starts by dividing by 26, going incrementally between each value.

She first take 26 into the first three numbers of and gets 5, then takes the remainder of 24 and brings down the 8 to get She then divides by 26 to get 9 with a remainder of She then goes into some detail as to how to extract the decimal from the remainder by continuing the long division and adding zeros to the end of the divisor.

Line integrals will no longer be the feared terrorist of the math world thanks to this helpful guide from the Khan Academy. Marvel at the ease in which the integral is taken over a closed path and solved definitively. Then take out a sheet of paper and see if you can do the same.

This how-to video shows viewers how to solve math problems with brackets in polynomials. The person in the video teaches people how to solve the problem with a positive sign before the brackets. This segment does not show how to solve the trickier problem where there is a negative sign in front of the brackets.

The sum is 3. However, if -8 and 3 are added, the sum is In terms of the number line, -8 is further to the left than 3 is to the right. Speaking math language, if a positive number is added to a negative number and the absolute value of the negative number is larger, the sum will be negative.
