SHORT TRICK TO MULTIPLY ANY TWO DIGITS NUMBERS.

You should observe to learn the working of this method.

Step - 1: Multiply the unit digits (rightmost digits) of both the numbers,

Step - 2: Add the cross product of the digits as shown below:

Step - 3: Multiply the ten’s digits (leftmost digits) of both the numbers.

Note: If the results obtained in step 1 and step 2 have more than one digit, note down the unit place of the result and carry over the ten’s place of the result to the left. Let us understand the process through some examples:

Example 1: Solve 13 × 12

Step - 1: Multiply the unit digits (rightmost digits) of both the numbers,

Step - 2: Add the cross product of the digits as shown below:

Step - 3: Multiply the ten’s digits (leftmost digits) of both the numbers.

So,13 × 12 = 156

Now before you get too excited, I have shown you only half of what you need to know. Suppose the problem is

Example 2: Solve 28 × 35.

Step- 1: Multiply the unit digits (rightmost digits) of both the numbers,

Step - 2: Add the cross product of the digits as shown below:

Step- 3: Multiply the ten’s digits (leftmost digits) of both the numbers.

So, 28 × 35 = 980

IT COULD BE SIMPLIFIED LIKE THIS

There are some more examples like this

Note: After knowing the procedure correctly and after some practice,

students will be able to get the answer only in one step as follow:

Example 3: Solve 78 × 47

(Now, You are advised to practice this exercise till you are able to solve all 5 questions in 1 minutes)

1. 65 × 87
2. 76 × 43
3. 69 × 31
4. 83 × 42
5. 99 × 43

Short trick to multiply any two digits Number by 11.

5 BEST REAL LIFE APPLICATIONS OF ANGLES.

As you probably know that the Angle is the measure of rotations taken by a ray around its initial point. But, have you ever thought what could be the practical applications of Angles in real life ? Position, direction, precision, and optimization are some reasons why people use angles in their daily life. In this post you are going to learn about the 5 best practical real life applications of Angles. So let’s dig in. 1.) At Street Intersections – Street intersections are made at angles as close as possible to 90°, if not greater, so that visibility is easier when turning. It is beneficial for city planners to create additional turns so that there are larger turning angles for safer traffic. For example, if a car has to make a sharp 60° turn onto traffic, it would probably be more likely to get into an accident because the turn is difficult. If you find a non-perpendicular four-way intersection with a stoplight, it is likely to have a “No Turn on Red” sign for those drivers who w...

REAL LIFE APPLICATIONS OF TRIGONOMETRY | REAL LIFE MATH.

Triangle trigonometry has many applications that help find unknown lengths or angle measurements. For instance, paintings, motion pictures, and televisions have ideal viewing distances in order to create the greatest possible image from the eye. The triangle is formed between the view and the top and bot- tom (or the sides) of the viewing object. Here are the 5 best Real Life Applications of Trigonometry. 1.) In Astronomy Astronomers use triangle trigonometry to determine distances and sizes of objects. For example, the distance from the earth to the moon, and earth to the sun, can be found by identifying their angles from the horizon during an eclipse. The height of a solar flare can also be determined by measuring the angle from the sun to the tip of the flare, and using distance information about the earth and sun. 2.) In Engineering Work Trigonometry can be used to find unknown lengths or angle measurements. In a situation involving right triangles, only a side le...

BEST WAY TO CLASSIFY AND DEFINE THE NUMBERS.

Numbers are the basic terms to embark upon any counting. Can we make any calculation without the help of any number ? Moreover, can you even count your fingers without using any number ? The answer is , No. In this post we are going to learn about what the numbers really are and how could be classified on the basis of their properties. Can you answer the question "What is a number ?" The answer is " A number is an arithmetic value that represents a particular quantity. It is expressed by symbols, words and figures. It is used in counting and making calculations." It probably looks like a theoretical note but, it is the explanation of a number. Now we are moving towards Types of Numbers. Natural Numbers - Numbers that are naturally used in counting are called natural numbers. They are denoted by N. These are ; (1,2,3,…so on.) Whole numbers – If o is also considered as a number then natural numbers and 0 together made set of nu...
