Perhaps not as easy as using a calculator, but easy nevertheless! With mathematics, as with anything else, not everyone progresses at the same rate. Happily, in the age of Internet video tutorials, this isn't a problem. Those who progress quickly can go beyond what's being taught them and those who are struggling likewise have all the time in the world to catch up. With this free video math lesson, you'll learn how to find square roots by hand.
In this tutorial, we learn how to find the area of a circle. The line from the middle to the edge of the circle is called the radius. Find what this is in your equation, then multiply (3.14 X radius x radius). This will always work out the area of a circle for you. So, do this equation with your calculator or by hand, then you will have the correct answer for the area. Make sure to add the units squared after you get the answer. If you are given the diameter (line all the way across), you wou...
In this video we learn how to convert recurring decimals to fractions. Start off by writing out the decimal with the dot next to it to show that it's recurring. This means that the number goes on forever and doesn't stop. To convert this to a fraction, write down the number as the numerator. On the bottom you will put the number 9 always. Now, you can divide these two numbers with each other using a calculator. Once you do this, you will get the correct answer. Once you divide it out, you wil...
In this video, we learn how to find the area of a trapezoid. The formula to figure out how to find the answer is: Area= 1/2x (base1 x base2) x height. Now, find the bases and the height of the trapezoid. Remember that the height must always be perpendicular to the bases. Once you have found these, add the bases and multiply by the height. You can use a calculator to do this or do it off hand if you're good with math. For the third step, divide the answer by 2 and then write down the answers w...
In this tutorial, we learn how to convert a fraction to a decimal. Start of by dividing the top number by the bottom number. You can do this by hand by writing out the long division of it, or you can use a calculator. If you choose to do this by hand, the bottom number will be on the outside of the division sign, and the top number will be on the inside. Once you have divided this out, the answer will be the decimal that you come up with. Continue to practice doing this will different numbers...
In this tutorial, we learn how to divide fractions into decimals. First, you will want to divide your numerator by your denominator. If you can simplify this number further, it will make it easier for you to divide. You can do this on the calculator, or you can do it by hand. The numerator will go on the outside of the division sign and the denominator will go on the inside. When you divide, you will come up with a decimal. If you have an improper fraction, you will probably end up with (1.so...
