Fastest Mental Multiplication Math Tricks - 2 Seconds Multiplication Trick

826 views 3 weeks ago
Fast Math Multiplication Videos Tutorials - This is a unique fastest mental math multiplication trick which will teach you to multiply in your head taking number from 0 to 10. There are many fast mental math calculation methods, this one will teach you to multiply any two digit number by 9.
Steps of The Fastest Mental Multiplication Tricks:
1. Imagine 1 to 10 number line in brain.
2. Write in brain first digit of the two digit whose fast multiplication by 9 we need to do.
3. Figure out the total number of digits between first and second digits. Like if its 25 then there are 3 & 4 , two digits in the middle , so write the difference number there ( here 2)
4. Now , figure out how many digits are more to reach 10 from second digit and also write it down .
5. See the 3 figure number, that's you answer.
6. sometime the difference between first and second digit can be zero. like 45, in such cases write zero.

There is condition to apply this fast mental multiplication trick
- The Ones Digit should be bigger than tens. I mean you can apply this trick to 39 but not 93, this rule will apply for 49 but not for 94.

Limits & Continuity Play

This Limit& continuity videos playlist gives complete concept of limits & continuity of a function. Video lesson are arranged in ascending order of concept to get maximum output knowledge of limits of a function and continuity of a function. The video playlist contains all varieties - like conceptual videos, question solved videos, examples, illustrations all related to learning limits and calculation.As the concept of limits & continuity of a function is the basics of calculus math, so it very important to learn these video lesson.
These video explanation are useful for school students starting to learn calculus in first year like 11th class ( grade) students . The videos of limits and continuity are being added frequently so, be up to date with the concept of limit of a function or continuity of a function. Once we understand , what is limit of any function , either algebraic or trigonometric or logarithmic or exponential function, we learn to find limit of those functions. All different types of limit questions are solved in this playlist- hard question on finding limit of a function to easier one example of finding limit. After good practice on finding limit, we will jump to continuity of a function. Checking continuity of a function is very essential skill in calculus, so , we learn all tricks and tips to check continuity of a functions. Many functions are discontinuous at many points, so, we will learn how to check continuity as well as discontinuity of any function. I believe, this limit & continuity playlist will help you very nicely to gain more and more concept of limits & continuity for learning derivative of a function.

Application of Derivative Play

Application of Derivative playlist contains all the concept containing video for application of derivative chapter in mathematics. Derivative is applied not only in mathematics but it widely used in many other subjects - engineering, physics, chemistry, economics, business math etc. Application of Derivative is very important concept . This playlist contains how we can use derivative - how we can apply derivative concept for measure of rate. Similarly we can use derivative to find whether the function is increasing or decreasing. Similarly we can find the maximum and minimum points of any function with application of derivative. We can easily find the equations of tangents and normal using derivative concepts . I hope this playlist will help you a little in gaining concept of calculus...

Anti-Derivative (Indefinite Integration) Play

Anti-Derivative commonly known as Indefinite Integration includes complete video lesson required to Master the Integration calculus. This Anti Derivative, indefinite integration playlist carry video lesson from basic concepts of integration, geometrical meaning of integration to higher level question. Please watch the video one by one in sequence from this Indefinite Integration playlist to get better result.

Vectors and Scalars Play

Vectors and Scalars playlist contains all the concepts required to learn vector mathematics or vector physics. This Vector Lessons are from beginning level to high school level mathematics managed in systematic order. First we learn 2D vectors then we learn 3D vectors. Vector Tutorials playlist starts from concepts of vectors are scalars and then different types of vectors like unit vector, null vector, coinitial vecotrs, collinear vectors, and many more..then we learn addition of vectors. We learn how to add two or more vectors using laws like triangle law of vector addition, parallelogram law of vector addition, polygon law of vector addition etc. Then we learn products of vectors like dot product of vectors which is also called scalar product of vectors and then we learn cross product of vectors or vector products..and so on....

Set Theory Play

This Set Theory tutorials lesson contains all the required concepts of set theory in mathematics. Set Theory in Mathematics is very conceptual , therefore, this set theory tutorial lesson cover from basic concepts of set theory to higher level concept . This is a great resource to learn set theory in youtube from your home.

Trigonometry Play

Learn Trigonometry from basic concepts. This Videos Playlist contains all video lesson covering all most all concept required to learn this Chapter. It contains video lectures from introduction of trigonometry to higher level college trigonometry concepts, covering concept, examples, illustrations, practice questions, proving questions etc.
Trigonometry is one the most usable chapter of mathematics and is so much linked chapter with other branches of science and of course mathematics. So, It is very necessary to learn This chapter of Mathematics is very conceptually, otherwise it will be difficult to learn other topics of mathematics as well like, relation and functions, derivative calculus, limits and continuity , integration etc.
This trigonometry video playlist starts with the concept of trigonometry, which start from a right angled triangle and then we learn major 6 trigonometric ratios, sine, cosine, tangent, cotangent, secant, co-secant, after learnt these trig ratios, we learn their values for different angles. We learn trigonometric values of o degree, 30 degree, 45 degree, 60 degree , 90 degree and so on. Then we learn few tricks to remember these trigonometric table values. After that our next trigonometric lessons are on - based on solving trigonometric ratios question including simplifying, proving etc types of question.
After that, anther level of learning trigonometry is - learning trigonometric identities and their uses. There are so many identities to be learnt in trigonometry. These are very important as they help us to convert one trig ratios to anther and gives concept of trigonometric expression, terms and functions. There are so many types of proving question based on trigonometric identities from simple level to very hard, difficult question. We learn to solve all those types of trigonometry questions to solve in many video lesson.

Then we start learning second level of trigonometry , where we increase our concept of trigonometry and start learning with the help of circle in four quadrant. In the first level of learning trigonometry , we focus till 90 degree but now we learn trigonometry till 360 degree with generalization. We learn trigonometric ratios for half angle, double angle, thrice of angle etc.. We learn various types of trigonometry formula which includes trigonometry conversion formula, trigonometry transformation formula, inter conversion between sum of trig ratios to production form and vice versa and many more. Later we learn the generalization of trigonometric functions of sine, cosine and tangent and their curves.
The trigonometry video lesson are being added everyday, so please be up to date to learn more and more concept of trigonometry.

Application of Trigonometry Play

This Application of Trigonometry playlist contains trigonometry word problems like Height & Distance problems which will give you some good tips on how to find height of a tower, or which ratio will be appropriate , how to use trig ratios in word problems etc...
