In this tutorial, we learn how to divide numbers with exponents. The quotient rule states that we can divide two powers with the same base by subtracting the exponents. With the same base, you can subtract the exponents to get something that would be the answer. For example, if you have 6(to the fourth) divided by 6(to the second), this would come to equal 6(to 4-2). This would break down to equal 6(to the second power). Once you have this, you will be able to do the math for this and figure ...
In this video, we learn how to solve a single-step equation using multiplication. For the first step, get rid of any number surrounding the variable. To do this, you will need to multiply the numbers around it by their opposite to make them equal zero. Once you have done this, you will need to repeat the process on the other side of the equal sign. Just do the same exact thing you did in the first step, then you will be able to easily solve the problem at hand. You can check your answer by re...
This video tutorial is in the Education category which will show you how to evaluate a line integral along a straight line segment using the definition of the line integral. This video evaluates a line integral along a straight line segment using a parametric representation of the curve (using a vector representation of the line segment) and then integrating. A vector representation of a line that starts at r0 and ends at r1 is r(t) = (1-t)r0 + tr1 where t is greater than equal to 0 and lesse...
In this video, we learn how to back out the tax from a receipt. If you have a receipt where you see how much you paid and know the tax rate, except you want to figure out the cost of the item before the tax. First, take the cost of the item including tax and what the tax rate is. To figure out the original price, let x equal the cost of the item. Add the tax to the cost of the item which will equal the cost you paid. Perform the equation 1x+(tax rate)= (total price). After you figure this equ...
If you would like to create the look of stitches or sutures on your clay sculptures, you will need the following: clay, a toothpick or sharp implement, and a cutting tool.
Exponent of a number is nothing but the number multiplied to it self the exponent number of times. So five squared it equal to five multiplied to it self. Now when an exponential number is divided with another such number the result is the number raised to the different of the exponents. That is the ratio of x raised by a to x raised by b is x raised to (a-b). Similarly if we multiply a exponential number with other such number, the result is equal to that number raised to the sum of exponent...
Have you ever thought about creating small boxes out of newspaper? Tomoko Lipp shows you a simple folding and cutting method to do this.

In this video, it is shown how to calculate the area of a circle where the diameter is given. The formula for calculating the area of a circle is pi multiplied by square of radius. Radius is actually half of the diameter. In this video, the diameter is given as 10.6 meters. Hence, the radius will be half of 10.6 which is equal to 5.3 meters. Now, to find the area we shall multiply pi with the square of 5.3. Square of 5.3 is 28.09. If we multiply 28.09 with pi we shall get the area of the circ...
You need to have three kinds of ingredients – Vanilla vodka, pumpkin spice liquor, and Baileys. Find your martini shaker and fill half of it with ice. Add one ounce of vodka, one ounce of pumpkin spice liquor and one ounce of Baileys all in equal parts. You do not need to measure it exactly; you could just pour them into the shaker just approximately in equal parts. Put the cap on your shaker and shake until the outside of the shaker is frosty cold. Then pour the contents of the shaker into a...
This tutorial looks at how to describe a linear system without actually graphing it. In order to do that, you will need to convert both equations of a problem into the Y=mx+b format. Once you have done this, you will be analyzing the m and b values. There are a few rules to follow. If the slopes (or m) and the Y intercepts (or b) are equal, there are an infinite number of solutions (or dependent equations). A second rule is if the slopes are equal and the Y intercepts are different, then the ...
In this video the instructor shows how to solve quadratic equations by factoring. You can solve a quadratic equation by factoring them. To do this first write the equation in the standard from which is a*x*x + b*x + c = 0. Now factor the equation into two smaller equations of single degree. Now you can apply the zero-factor property to solve the equation in this from. The zero-factor property states that for a real values a and b, if a multiplied by b is equal to zero then value of a must be ...
This is a very interesting mathematical instructional video on how to find rational equation with no solution. How to solve the equation and check the answer. Let us take the example m over m-3 minus 4 is equal to 3 over m-3. In this equation we get m-4m+12 over m-3 is equal to 3 over m-3. When we simplify it further we get -3m +12 = 3. Or -3m = -9 and m = 3. This video teaches you very clearly how to solve a rational equation with no solution.
This video teaches how to calculate the acceleration of a car. The information for this calculation is for a car that accelerates by 12 meters per second in a time of 3 seconds. So to calculate acceleration use the following formula: acceleration equals change of speed divided by time. So, using the information provided for this calculation, acceleration equals 12 meters per second divided by a time of 3 seconds. So this gives an acceleration of 4 meters per second squared.
Learn the correct method for graphing inequalities on a number line. Inequalities are, simply, mathematical comparisons between numbers or expressions. Numbers and other expressions can be greater than, less than, and/or equal to other numbers or expressions. Typically, this is indicated in mathematics through the use of the less-than (<) and greater-than (>) signs, along with the greater-than-/less-than-or-equal-to signs. Using other special notations, which you will learn in this video, the...
Calculating The Area Of A Parallelogram A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:
This video shows you how to easily find the perimeter of a rectangle or even a square. The perimeter is the total length of the path that surrounds the area of a rectangle or a square (in this case). For a rectangle, the perimeter length is equal to 2L+2W, where L is the length and W is the width. For a square, the perimeter length is equal to 4L, where L is the length or simply one side. e.g.: L=3, W=2 => P(Perimeter) = 10. That's it! Good Luck!
In this video the tutor shows when to use a dotted line and when to use a solid line while graphing lines in coordinate geometry. He says that we should use a dotted line to plot an inequality which contains the symbols less than or greater than. He also says that we should use a straight line when plotting an inequality which contains the signs less than or equal to and greater than or equal to. He goes on and demonstrates this idea with some examples. This video shows how to use different l...

In this video you can learn how to solve linear inequalities. Understand the basics of inequalities and linear equations. In an inequality, we say that that one number is greater than (>) another number or less than (<) another. On occasion we say that something is greater than or equal to, or less than or equal to. In a basic linear equation, we solve for the variable of x by subtracting the value from the opposite side or the = sign. Start by writing your equation on a sheet of paper. It wi...

This video tutorial is in the Education category which will show you how to convert Fahrenheit to Celsius in your head. This method is a good estimate for converting temperatures. However, do not use this for accurate temperature conversions. Let's say you want to convert 22 degree Celsius to Fahrenheit. 1st step is to double the figure, that is, add 22 plus 22 which is 44. Next add 44 with 30, which gives the result 74. So, 22degree Celsius is equal to 74 degree Fahrenheit. Similarly, 32 deg...
