How to use "we half it,we square,we add it to both sides" when using the complete the square" This method can help make a complex Math problem a little bit easier.
This video has 7 fraction hacks that can save you time when working with fractions. The hacks are:Adding fractions without a LCMFractions you must memorizeThe circle methodThe ladder method for LCM and GCFWhat is the name of the fraction barAlternative to the criss cross methodKeep Change Flip
The key to simplifying fractions is to convert the fraction from a hamburger to a hot dog. In other words you change it from a fraction to a division problem, and then use Keep,Change,Flip to simplify. The video explains all of this and helps make complex fractions,simple.
If you have a rectangle and the length of only one side is given,how do you find the perimeter. The video shows how the diagonal creates a right triangle. This right triangle can be used to find the other side of the triangle, and then the perimeter.
Learn how to find the area of an equilateral triangle. Apply the formula for finding the area of an equilateral triangle. Solve an example problem calculating the area of an equilateral triangle.
30-60-90 triangles have properties that allow you to use shortcuts in order to find leg lengths and the hypotenuse. For example, if you know the hypotenuse you can use these shortcuts to find leg length.

Midtown Delivery Service delivers packages which cost $1.30 per package. The fixed cost to run the delivery truck is $175 per day. If the company charges $8.30 per package, how many packages must be delivered daily to break even?
Struggling to find and calculate the correct consumer surplus for an econ class or in any other situation? Take a look at this guide that will walk you through the different equations and graphs necesssary to understand and calculate consumer surplus.
Algebra is not as hard as it looks. Learn how to evaluate expressions correctly by using the order of operations, which can easily be remembered as PEMDAS- Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. You can solve any problem in algebra with this approach.
Can you dissect an equilateral triangle into pieces that can be rearranged into a square? If you think you can, you may have mastered the Pythagorean theorem.
Adding and subtracting may be the easiest of mathematical operations, but once you get it down, multiplication and division can be just as easy. That's why it's called elementary arithmetic. If it were harder, it would be called college algebra or trigonometry. But it's not— it's basic math, and once you get your head around the numbers, you'll never hate math class again! (Okay, maybe you will.)
For someone who loves math as much as Vi Hart (a self-proclaimed "mathematical musician"), she doesn't pay an awful lot of attention to her math teacher. But that's ok. Cuz somehow her wonderfully whimsical doodling transforms into mini lessons on graph theory, mobius strips, binaries, fractals and more.
Have an old-school tabula recta lying around? No? Then just print out the chart below. Nothing ensures better password security than this centuries-old cipher technique. Here's how it works, via Wikipedia:
Meet Vi Hart, our charming host. Vi is a self-labeled "mathematical musician", who burns paper instruments, cuts food into mathematical shapes, twists balloons into mathematical models, and makes mathematical music with candy buttons.

This is a video tutorial in the Education category where you are going to learn how to factor a trinomial by GCF then grouping method. For example how to factor the trinomial 6r(squared) â€" 28r + 16. The first thing is to get the greatest common factor (GCF) of the numbers. So, GCF of 6, 28 and 16 is 2. The trinomial can now be written as 2{3r(squared) â€" 14r + 8}. To factor by grouping, see the trinomial as the general formula of ar(squared) + br + c. To factor this, you got to look at the...
In this video, we learn how to use probability to predict weather. Probability is the chance of something happening. If you want to know what the weather is going to be like, you can look at the weather report and see what each day is going to do throughout the week. Ask yourself what the probability is that the weather will be cloudy, judging from what the current work week weather is. First, figure out how many days there are total and then find out how many are cloudy versus how many are...
This is a video tutorial in the Education category where you are going to learn how to write equations in pre-Algebra. Write an equation that represents the following sentence and then solve the equation. The product of n and 6 is 12. That's n multiplied by 6 or 6n = 12. We want to solve our equation for n. That is we want to get n all by itself on the left hand side. Since n is multiplied by 6, we got to divide both sides by 6. So, we get 6n/6 = 12/6. On the left hand side of the equation, 6...
Radical expressions are those in which the radical symbol (under root sign denoting the square root or the nth root) is present (either multiplied or added). Solving these is a bit tricky, but involves similar algebraic maneuvers in a different way.
This video begins with an explanation of the general rules to be followed while solving such mathematical problems. The concept of simplified form and its importance is also explained.
The later half of the video explains the concept once more...
The Pythagorean theorem is a simple theorem that states that - for a right angled triangle the square of the length of the hypotenuse is equal to the sum of the squares of the length of the remaining two sides.
In this video, a right angled triangle with three sides, namely a, b and c is shown. One side "a" is of unknown length. The length of the other two sides are given. This problem is then solved using the above mentioned theorem. As expected, a bit of basic algebric manipulation (linear...
