In this video tutorial, viewers learn how to find the area of a rectangle. The formula for finding the area of a rectangle is: A= b x h. The base is the horizontal bottom lie of the rectangle and the height is the vertical straight line of the rectangle. Whenever working with area, users must square the unit of measurement. To find the area of a square, multiple the side of the square twice (square it). This video will benefit those student viewers who are struggling with math, and are in nee...

Keep the squares in the order you picked them. Layer the squares on top of each other, pinning them together. Then, sew the scarf straight dow...
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...
If you've ever wanted to learn how to build a LEGO chicken, today is your lucky day. First you'll need a 1x1 red LEGO stud, flat square with claw, smooth white, orange with a tooth, flat square, and a flat square with a circle coming out of the side. Starting with the claw, but the stud on top. Now take the piece with the claw and attach that to the opposite side of the claw. Put your flat square on top of that, then the flat with the tooth and another flat square goes on top. Now you're done...
In this video, the instructor demonstrates how to solve radical equations and inequalities. If you have an equation that contains radicals, re-,arrange the equation so that all the radicals are on one side and the integers are on the other side. To cancel a square root from an equation, square both sides of the equation. The square of the equation cancels out the square root, thereby removing the radical. Even after squaring if you still have a radical left, treat it as a new problem and appl...
In this tutorial the instructor shows how to complete the square to graph a quadratic function using transformations. You can do this by transforming your equation in a series of steps. First make the coefficient of the square term to one by pulling out its numerical coefficient. Now to complete the square of the first part add half the coefficient of the variable with a degree one. Now to maintain the original value of the equation also make sure that you subtract the same value from the equ...

Pythagoras was a smart man, so smart that his mathematical theory is named after him and still used today, more than 2,000 years later: the Pythagorean theorem. It implies that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. The Pythagorean theorem is a cornerstone of geometry. Here’s how to use it.
This video shows how to tie a scarf three different ways. The first way to tie a scarf involves a square silk or chiffon scarf. Fold it and wrap it around your neck, then tie it to one side. This is like an ascot tie. The second way to tie a scarf requires a long scarf. Tie it around your waist like a belt, with the ends dangling down your side. This creates a scarf belt. Finally, choose a shorter scarf. Tie it around your head with the tie in the back. You can tie it over your hair. Or you c...

The Square-1, also known as Back to Square One and Cube 21, is much like the Rubik's Cube, but its shape changes when twisted, adding an extra level of difficulty.
In this tutorial, we learn how to use the distance formula for two points. The distance formula is D= the square root of (X2-X1) squared, plus (Y2 minus Y1) squared. It may look confusing, but it's just a derivation of a theorem. First, find the two points that you have and graph them. If you want to know the distance between them, you cannot just count squares if it's a diagonal line. If you remember geometry, you can draw a right triangle over the line to figure out the distance. After this...
In this video, we learn how to make a mosaic picture frame with ceramic micro tiles. First, glue on the four gemstones. These will go on all four corners of the frame. Next, place the square mosaics onto the base. You will place these around the edges of the frame that are perfectly square. After this, cut the other squares in half and glue them onto the entire frame in the middle of the squares on the frame. Next, let the frame dry for two hours, then mix the powder together with water and r...

YAYMATH. This video is a demonstration of usage of the distance formula to find the distance between two given (x,y) points. In this video, the tutor guy who is teaching the distance formula to his students takes an example of two (x,y) points such as (5,-1) and (11,7). He then writes the distance formula on the board. The formula goes like this, the distance between two points, denoted by 'd' is equal to the square root of the sum of the square of (x2-x1) and the square of (y2-y1) where (5,-...
This video teaches three different ways to fold a pocket square with a handkerchief. The three different folds are the straight fold, one point fold and puff fold. To make the Straight fold: Fold the kerchief into half from the side and fold the bottom to the top leaving some space at top .

Does a bob haircut remind you of flappers from the 1920's? Originally, the hairstyle (as worn by flappers) was meant to be an androgynous cut, boyish in length and style.
Just as not all face shapes were created the same, not all hairstyles were created equal. In fact, a gorgeous blunt-cut pixie do may look dazzling on your oval-faced friend, while it would make your round face look larger.
In this video, we learn how to rationalize the denominator. This says that if there is a square root or any type of root, you need to get rid of them. Look at the examples given in the video to get an idea of what types of roots you will be removing and how to do it. To get rid of a square root, all you really have to do is to multiply the top and bottom by that same square root. Do this on all of your problems with a square root and they will be gone in just a matter of minutes!
