So finally here we came up with this shortnotes on Probability which really helps you in getting good marks in Probability and Statistics section of Maths in Bank and all Competitive Exams. In this notes we've started with the basic details like definitions and later explained the concept with problems. We've tried to give detailed explanation for every problem we've mentioned in this small book. Good Day and Happy Reading :)

Trachtenberg Speed Maths - Pdf

Friends, today we are giving you one of the useful books on mathematics. That is The Trachetenberg System of Speed Maths. And before going to download and read the book, lets read a small story of our hero Jakow Trachtenberg (The inventor of a system of rapid mental Calculation known as The Trachtenberg System). He created the Trachtenberg system of mathematics, whilst a political prisoner in Hilter's concentration camps during the second world War. To keep himself sane whilst living in an extremely brutal and harsh environment, Trachtenberg immersed his mind in a world of mathematics and calculations. As concentration camps do not provide books, paper, pen or pencils nearly all of his calculations had to be performed mentally. This forced Trachtenberg to develop methods and shortcuts for performing calculations mentally. Trachtenberg developed his discoveries into a complete system of mathematics.

Math Tables in Audio (Mp3) format

First time in the history, Gr8AmbitionZ.com is proudly presenting Math tables in audio (Mp3) format. The concept behind this post is very simple. Its an open secret that most of us don’t know the answer of “What is Seventeen eights are!!!”. Ofcourse we do have some techniques to calculate the answer in our minds, but my question is “Why to waste those few seconds during the time of exam???”. We are posting the tables in audio format because It has been known for years that our brains can continue to take in and learn new information even while we are asleep. So why not use this to help those people who have great difficulty in learning their 'times tables'. These  files are numbered the same as the tables. i.e. the Ten’s times table is track 10; the Thirteen’s times table is track 13 etc. The tables cover the numbers from 1 to 20! You can use the files in two different ways :

Shortcut for finding Cubes

Attention Friends... we've came to know that this method is not working for some numbers... So presently we are working on more efficient method than this... We advise you to avoid this method....

In our last posts we've discussed the method of finding Squares (read that post Here). In this post we shall discuss the method of finding cubes. This is very easy and simple method. You just have to put little concentration while learning and should do little practice so that you can do the process in a easy way mentally. And another thing you should keep in mind is, we are posting the step by stem inorder to make you understand the process in detail, but you SHOULD do most of these steps MENTALLY and only should put some important final results on paper. Now lets have a look at the method. In earlier method of finding squares we'd discussed finding the squares with the formula (a+b)² , here we shall use the formula (a+b)³. 

Lets start with an example. Assume that you should find out the cube of 18. The general process is multiplying 18 to itself for 2 times (18 x 18 x 18). This process is time consuming and often people end up with the wrong answer caused by confusion and hurry. 

Ok, now lets use our method. here you should use the formula  (a+b)³  = a³ +b³+ 3a²b +3ab². But here you should be little tricky. Have a look.........

Mental Maths (Comparison of Fractions) - Part 1

You have to Compare the given fractions in a number of problems in Data Interpretation and Quantitative Ability. Let us study some of the common methods of identifying out the largest or smallest of a given set of fractions which are useful for Mental Maths. 

Model 1 :

When the numerators are same and the denominators are different, the fraction with the largest denominator is the smallest. Have a look at the following example.

• Which of the following fractions is the smallest?
• (3/5) , (3/7) , (3/13), (3/8)

How to improve Maths / Aptitude Calculation Speed

Calculation Speed plays a very very very important role in Bank Exams. Some people think that, people should have the natural ability to do calculations fast, of course that is true at some extent. But that doesn't mean the other ordinary people like you and me need not feel bad.

According to Aerodynamics Laws based on Weight and the Size of the wings, some species only do have the ability to fly. If we strictly apply their laws, a Bee cant fly. Because its weight is More and Wing's length is very less when compared to its Weight. But still it is flying very comfortably and enjoying the Honey in almost every flower.

Sometimes Old rules and blind beliefs remain worthless. Forecasters' predictions become wrong. Only The Belief in You and Hard work will create wonders. Trust me, it is very easy to develop good calculation speed in a relatively short period of time. All you need is Hardwork, Little Amount of time and Good Material to Prepare... You give us the first TWO, we will provide you with the Third one... 

30 x 30 : Just spend 30 minutes a day for 30 days. You will definitely find the difference in your calculation speed. Your practice involves basic Additions, Subtractions, Multiplications, Percentage Calculations, Comparing Fractions and Calculating Squares. 

How can this blog help me? We post some examples on calculations. Solutions for these
examples indicating the short-cuts that you need to learn and implement. Which will help you to solve problems mentally in less time .

How to use this blog? Before you start involving with our posts, make sure that you are thorough with the following (Mandatory) :

• Powers of 3 (Up to 6)
• Reciprocals of numbers (Up to 12)
• Complements of 100 
• (I mean, the difference between 100 and the given 2 digit number).

Some Useful Shortcuts of Basic Maths :

• Addition Shortcuts
• Subtraction Shortcuts
• Multiplication Shortcuts
• Division Shortcuts
• Decimals

What should I do for this : Nothing, just open this page daily when ever you free. You can find a post containing 20 questions on calculations (Additions, Subtractions, Multiplications etc) . Just try to solve them mentally in the recommended time. Just put away your Calculators, Pens, Pencils and Papers. 

While taking these tests, please follow the below instructions.

• Take One test every day.
• Check the starting time and keep in mind the time that has been allotted for the particular exercise.
• Don't use calculator.
• Write as little as possible on paper. You should try doing as much of the calculation as possible mentally.
• Some questions require precise calculations whereas some other questions require only approximate calculations. Please remember that the level of accuracy to which you should work out the calculations will depend on the answer choices given in the post itself. So, do not spend more time than is necessary on each question. 
• Stop the test as soon as the Prescribed time is Over.
• After you Complete each exercise, spend time working out the questions that you could not complete in the given time. Then, check for the correctness of your answers. Rework all the questions in the test to see whether the method that you adopted was the best/shortest.
• Check the answers to see whether you have approached the calculations correctly. Use the learning that you gain in one Exercise in working out the next Exercise.
• Even after you use up all the tests given in this Blog, you should continue similar calculation practice on a regular basis to ensure that your calculation speed does not drop.
