In this video tutorial, viewers learn how to find an angle using alternate interior angles. Make sure that the angles are alternate interior angles. Alternate interior angles are angles that are on the inside of the parallel lines, and on the opposite side of the transverse. The transverse is the line that passe through the two parallel lines. If both angles are inside the line and are opposite to the transverse, then they are alternated interior angles. If you know two angles are alternate i...

Geoboards are fun tools to teach your child the basic concepts of shapes and how they work in math; any kid would love a gigantic one! Firstly, you need to obtain a pegboard (what they hang merchandise on in hardware and similar stores). They usually come in 4x8' sheets, so you may need to ask an employee to cut one into fourths for you. The fourth piece should have 64 holes in 8 rows of 8, which means you need 64 nuts and bolts to make the board. Assembly is a no-brainer; you and your kids s...

In this video the instructor shows how to identify patterns in numbers, figures, letters. When given a pattern like 1, 2, 4, 7 try to find the change in each of the successive numbers in the pattern. If you observe carefully you will notice that the difference of the second and first number is one. Similarly the difference of the third and second number is two and this pattern keeps repeating. So this pattern is generated by taking 1 and adding 1 to it. To the next number add 2 to get the thi...
In this video the instructor shows how to simplify radicals. A radical is nothing but another name for a square root. To find the square root of a simple number the first thing that you need to do is factor it. If you need to compute the square root of a number, you first need to find a number which multiplied by itself gives the original number under the root. For example, to find the square root of 9, you need to find a number which multiplied by itself gives 9. Here the answer is 3. When 3...
This video revolves around solving rational equations in Algebra 2. When you are given a rational equation, you have to find the greatest common factor and multiply all fractions to get that common factor. If a fraction already has that common factor, then no further step is necessary for that one. Next, you have to multiply all fractions by the greatest common factor to get rid of all denominators. Finally, the remaining equation is simple math and you only need to solve the equation for the...
Are you slightly rusty on your math skills? This video demonstrates how to find the volume of a sphere with a given radius. The first step is to sketch a solid and cross-sectional view of your sphere to get an understanding of the process to come. Next, find a formula for the area of this cross-section. Third, find the limits of integration. This will allow you to take the area of each cross-section in the sphere, not just the singular one you are viewing. Lastly, integrate this formula from ...

In this tutorial the instructor shows how to simplify complex fractions. A complex fraction is the same as a normal fraction, but has a fraction problem in the numerator and a fraction problem in the denominator. The first thing to do is arrive at a simple fraction both in the numerator and the denominator. To do this take the lcm of the denominators of the fractions in the numerator and simplify it. Similarly do this in the denominator. Now both the numerator and the denominator have a simpl...

There will be a time when the need to know how to convert a percent to a decimal will arise. Maybe it will be when trying to calculate a percentage discount on an item to be purchased. The item is 30% off, but what does that mean? How do you calculate the discount if the original price is $92? Learn how to easily convert percent to decimal by following these easy instructions. Percentage means "per 100." In other words, 50% means 50 per 100. The easiest way to convert percentage to decimal is...
Watch this video to learn how to multiply fractions by fractions. First multiply the top numbers together. For example, if you have 3/5 * 4/7, multiply 3 * 4 and put your product on top of the fraction you will get as a product. Next, multiply the bottom numbers together and put them on the bottom of your resulting fraction. Next see if you can reduce your product to simplify it. You could also do the reducing step first by canceling out any common factors in the numerators and denominators o...

A representative from Math Problem Generator explains in this video that converting a simple fraction from its current state to a higher equivalent can be very simple. He explains the process neatly and provides a great example. To convert a fraction, you must multiply the numerator and the denominator by the exact same number. The example he shows is captured from the screen of a computer and is written out in some sort of a painting program. The example shows that four-ninths equals eight-e...
This video shows you how to easily remember "greater than" and "less than" math symbols. The first thing you have to remember is that "less than" symbol looks like the letter L ("less than" symbol is "<"). When you see this sign, remember that < looks like L and means "less than". The other symbol, "greater than" does not look like the letter L, therefore it cannot be "less than" and it's easier to remember. The "greater than" symbol is ">". That's it! Good Luck!
