Let me start out by saying that Steampunk isn't about being historically accurate, and that everything I'm about to tell you is entirely optional. That said, let's take a look at the history of screws! What many people don't realize is that before we had metal screws, wooden screws were in wide use for things like wine and oil presses. Generally, the invention of the screw is attributed to Archimedes in the 3rd century BC. That was a long, long time ago. Metal screws and even screwdrivers hav...
In this tutorial, we learn how to add rational expressions. When you have two rational expressions, you will first need to factor every denominator. After this, find the lowest common denominator from all of them. After this, rewrite every fraction so it has the lowest common denominator for the denominator. Leave it in factored form for the denominators. Multiply the top and the bottom to find the answer for each of the fractions in the equation. When finished, make sure you find the most si...
In this tutorial, we learn how to subtract rational expressions. If they have different denominators, you will first need to get them the same denominator. To do this, you will need to find the lowest common denominator. Factor the denominators that you have and figure out what the lowest common denominator of each of them are. From here, you can simplify the rational expressions in your equations. Next, you can go across the board and subtract the fractions from each other. To finish this up...
In this video, we learn how to add and subtract fractions with numerical examples. First, write down an example on a piece of paper to add two fractions together. To do this, you will write out the denominator in the common form and then add the numerators together. If you don't have common denominators you will have to find them. When subtracting, it's basically going to be the same process. Go through the same steps to figure out what the answer will be. Use the basic rules of math to get t...
Running on natural terrain - we're talking forests, hills, etc. - is nothing at all like running on flat, paved concrete. But despite this fact many runners who switch from concrete to a natural trail don't change their running technique to adapt to the new terrain. This is not a good idea because it can cause serious injury.
In order to subtract mixed fractions, you'll need to look at the denominators carefully. If the denominators do not match, you'll need to find a common denominator. For example, 5 2/3 minus 3 4/5 do not have the same denominator. The lowest common denominator for them is 15.

How to tie a Eight Figure Knot.
This video gives you brief tutorial on simplifying expressions, or canceling out common factors. He starts out by answering the question "What is canceling?" and demonstrates a basic example. You find the greatest common factor between the numerator and denominator, which you then divide both by. This can also be done if you have variables in your fraction. He then shows it can be done the same way if you have binomials in your fractions. However, you must be careful that the denominator does...
Would you like to impress all your friends by making 23 different smileys/emoticons on Facebook while you chat with them? Some of them are simple and easy to guess because they are used almost everywhere, but some of them are not so common.
This video shows the method to simplify rational expressions. The example used in the video is multiple of 4 and x square plus multiple of 4 and x plus 1 or (4x^2 + 4x + 1)/(2x^3 + 11x^2 + 5x). As the first and last term is a perfect square we get the simplified numerator as (2x + 1)(2x + 1). Next, the denominator is simplified. Taking the common factor out we get x(2x^2 + 11x + 5). Now we factorize 2x^2 + 11x + 5. We get (2x + 1)(x + 5 ). Now, writing the terms in numerator and denominator w...

In this tutorial the instructor shows how to calculate the sum of reciprocals of complex numbers. If you have to find out the sum of the reciprocals of two complex numbers first you will have to find out the least common multiple of the denominators. To do this multiply the numerator and denominator of the first fraction by the second complex number. Similarly multiply the numerator and denominator of the second fraction by the first complex number. Now you will have two fractions whose denom...
