This video shows the method to multiply two digit numbers using the grid method. First make a grid of three rows and three columns. Put a cross in the first row and first column or the (1,1) position. Separate the ones and the tens in the number. In our example 43 is broken into 40,3 and 56 is broken into 50,6. Put these numbers in the remaining places in the first row and first column. Now multiply every number with the other and place it in the corresponding location in the grid. In our exa...
This video illustrates the method of dividing real numbers. The process is composed of the following steps -Step 1Take any two real numbers. Convert them to rational numbers taking denominator as one.Step 2Find the LCM of their denominators and multiply both the numerators and denominators by the LCM.Step 3Now find the reciprocal of the second number and move to the next step.Step 4Now divide the numerators obtained. The denominator are also to be divided and the quotient obtained should be r...
Professor ElvisZap teaches you about adding consecutive odd numbers. You can learn this faster by drawing squares near the numbers themselves. If you are doing 2x2, draw 4 squares. They will be arranged in columns of two. For 9 you will draw 3 columns of 3. 16 are 4 columns of 4. 16 is also 1+3+5+7, which are all odd consecutive numbers. 25 are 5 columns of 5, but also 1+3+5+7+9. If you start counting 1 as the zeros odd number, then 3 as the first odd number, the nth odd number will be (2xN+1).

In order to add mixed number in fractions, in a math problem, you will need to focus on the denominator. The denominator is the lower number in the fraction. The top number is called the numerator.
Rational numbers are numbers that can be expressed in the form of a/b, where a, b are integers and b is not equal to zero. Rational numbers are also called as fractions. Multiplication of fractions is very simple and straight forward. Two multiply two fractions a/b, c/d first multiply both the numerators to arrive at the new numerator. Next multiply both the denominators to arrive at the new denominator. Now the new fraction can be further simplified to arrive at the solution. Note that you a...
This video tutorial shows you how to multiply mixed numbers. When doing this the first thing that you want to do is put the mixed numbers into a improper fraction form. From this step you can simplify the numbers based on what you are using. In this case you can take out the 3 and 21 and simplify it to 1 and 7 respectively. From here you do the basic multiplication to get one improper fraction. Then turn this number back into a mixed fraction to complete your problem.
In this tutorial the instructor shows how to subtract mixed numbers with common denominators. He explains the method using an example. He does this by subtracting the whole numbers separately and also subtracts the fraction parts separately. Now he finally puts both those results side by side and if the obtained result is not further deductible, it gives us a new whole number which is our desired result. If you want to learn how to subtract mixed numbers with common denominators watch this tu...
A guy from the website Math Problem Generator explains, in this video, how to easily multiply mixed fraction numbers. First, he demonstrates that you need to convert both of the numbers to improper fractions. Then he shows that you need to multiply the two resulting numbers together. The resulting fraction is also improper, so it needs to be converted back to a mixed number fraction. In the example that he provides, he shows that one and a half multiplied by one and a third becomes two and a ...
A lot of phone numbers these days use letters so that you can remember them easier. For example, 1 800 BEST BUY or 1 800 FLOWERS.

With the problem 5 ¼ divided by 2 3/8, you should convert both mixed fractions to improper fractions. 5 ¼ becomes 21/4, when you multiply 4 times 5 and add one. 2 3/8 becomes 19/8, when you multiply 8 times 2 and add 3.
In this video, we learn how to divide bigger numbers. As an example, let's say you were dividing 843 by 13. To make this easier, write down the times tables for 13 down and keep adding up. After you do this, see how many times 13 goes into 84. Your table will tell you how many times it goes into the larger number. Thirteen will go into 84 six times, so write six on the top line above the four, then subtract 78 from 84 and write a 6 next to the 4. Now, work out the remainder and when finished,...
