In this video, we learn how to read numbers in Arabic. Make sure you are looking at the screen while reading the numbers, so you can get a visual key as to how the numbers look. As you start with the first number, you should learn how to say them in Arabic using the correct pronunciation as well. Each of the different numbers have a unique look in Arabic and should be written out correctly, because they can be mistaken for other numbers if not written out correctly. You can also write several...
In this Math Made Easy tutorial the author shows how to subtract positive and negative numbers. He says that because of the numerous combination of positive and negative numbers it adds to a lot of confusion. Now he shows a trick of how to add positive numbers to negative numbers showing that it's equivalent to subtracting the negative number from the positive number. He shows that if you want to subtract a negative number from a positive number we should actually cancel all the signs and the...
In this video, we learn how to convert numbers in and out of standard form. Standard form is a useful way of writing down very large numbers and very small numbers. To do this, you will look at the number you have and ignore the zeros that are just at the end. Then, write down the basic numbers. Put a decimal point in this number to make it between one and ten. Now, write down x 10 and put the power for how many places the decimal point moved to get to the new number. This will help you write...
In this language video tutorial you will learn how to say numbers 11 to 99 in Vietnamese. For the numbers from 11 to 19, you simply add the number to the word for 10, that is, Muoi. For example, 14 will be Muoi Bon (Bon = 4) and 18 will be Muoi Tam (Tam = 8). For multiples of 10, simply add Muoi after the number. For example, 20 will be Hai Muoi (Hai = 2), 30 will be Ba Muoi (Ba =3), 40 is Bon Muoi and so on. For all other numbers, simply add the number after the multiple of 10. For example, ...
1.Here 10-50 and 300-400 numbers are taken for example to generate the random numbers within the limit in Excel. We using the command of "randbetween" for generate the random numbers and we won't get the decimal or fraction values.2.Now type "=randbetween(10,50)" which means to generate the random value between the bottom value of 10 and top value of 50 and click enter now we will get 11 as random generated number.3.Do the same thing for 300-400 as "=randbetween(300-400)".You will the 303 wil...
In this tutorial the instructor shows how to convert a improper fraction to mixed number. In the example the instructor takes the denominator of the mixed fraction and writes it beside and keeps adding it self to the latest number and he keeps on doing that way generating a series until he reaches the value of the numerator. Now he counts the number of occurrences of the numbers in the series before the value of the numerator which gives the value of the whole number in the mixed fraction. No...
Understanding the Binary Numbering System and how to decode binary numbers.
In this video we learn how to multiply mixed numbers together. First, take your mixed numbers and write them into an equation. Next, convert the numbers both to top heavy fractions. Now, multiply the top numerators together and then the denominators together. If you can't work out the numbers in your head use a method by writing it out in a table. As soon as you finish and end up with a final fraction, you need to simplify this. Find how many of each number goes into the larger one and then t...
In this video, we learn how to write numbers in calligraphy copperplate. To write the number five, you will simply make the shape of the number, but add in a thick edge to the bump and curved edges to the end. To write the six, use a thick line on the side of the number and a thin line for the circle in the middle. To make the seven, the top should be curved and thick, and the lower line should be very thick with a straight edge. To make the eight, draw the number so that the left edge is thi...
In this video, we learn how to understand two digit numbers in Arabic. Start off by having numbers written out in Arabic on a screen in front of you.

The pronunciation to these numbers is key, because they can end up sounding incorrect or you could make a whole new world with the slip of just one letter. Practice this for the ba...
Math has always had the reputation of being nonimaginative, dry, and straight to the point, but mathematicians like to have fun, too! Perhaps that's why they invented imaginary complex numbers dealing with "i."
A complex number is half real (a) and half imaginary (bi), just like that Edward Cullen who makes your heart thump realistically but whose sparkly chest makes you wonder if he's something more.
This video shows you how to generate random numbers with decimals in Microsoft Excel.When generating random numbers you must have a lower and upper limit, so that your number will be generated between the two limits. For a number without decimals, you only have to use the "=randbetween" function. If you want to use decimals, you will have to use a different but similar function. Start by typing "=rand()". Next, you multiply this by the difference between the limits and add the lower limit. Fo...

The are many different position options such top of page, bottom of page, page margins, or current position. The customization options are as endl...
The author in this tutorial shows how to convert mixed numbers into improper fractions. A mixed number has a big number to its left, a numerator for the fraction part and a denominator too for the fraction part. Now to convert the mixed number to improper fraction we first have to multiply the denominator with the big number and add numerator to it which results in a new numerator. Now the improper fraction is the new numerator divided by the previous denominator. The author explains this con...
This video demonstrates, without narration, a trick to multiplying large numbers. To do the trick, just draw a diagonal line for every unit in the number and add up the number of times the lines cross.
This is a video tutorial in the Education category where you are going to learn how to convert top heavy fractions to mixed numbers. Top heavy fractions are fractions with numerators greater than denominators. Mixed numbers are combination of whole numbers and fractions. To convert 12/5, find out how many 5s are in 12. The answer is 2 and after you remove two 5s from 12, you are left with 2. So, 12/5 is equal to 2 2/5. Similarly, in 10/3, you have three 3s in 10 and you are left with 1. So, 1...
Everybody gets phone calls from those strange numbers you kinda sorta recognize. Is that an old friend? Is it the guy you met last week? What's that area code anyway? Get to the bottom of the mystery by using reverse phone book services. This video will show you to find the source of a phone number.
Making a factor tree is useful for us to see the factors of those numbers. Here we will take 12 and make a factor tree of it. Now we have to see those numbers with whom multiplication 12 comes. We will not take 1 and 12 here that is a obvious answer. We will take 3 and 4 there multiplication is 12. It will make the first branch of the tree now for the next branch we will take 3. 3 is a prime number 4 is not a prime number but multiplying 3*2*2 gives 12.
