__Shortcut Tips & Tricks To Prepare For Mathematics Exam__

__Shortcut Tips & Tricks To Prepare For Mathematics Exam__

**: Applicants are advised to practice as much as possible to know the best way to solve the questions.**

__Practice, Practice & More Practice__**: Before start practice for maths know all the key concepts to know the reason of the problems come in the maths.**

__Learn the Key Concepts__**: If you made a mistake, then you should analysis them and recognize what your analytical skills have told you. So find the error and try not to make it happen again.**

__Review Errors__**: Group of the students helps a lot in study in solving the logical problems such maths. So guys join any study group and become friendly with this typical subject.**

__Join a study group__**: We know mathematics has extremely large number of formulas and it is not simple to keep in mind forever. So you can memorize them by practicing questions. Now answer some questions each day and then practice the used formulas subsequently.**

__Short and Easy tricks to make mathematics easy__**: The easiest method to estimate percentages is to multiply figures first and agonize about the two decimal places later. Remember that a "percent" means a fraction out of 100, which means move the decimal two digits to the left.**

__Faster Percentage Calculation__**: 20% of 70? 20 times 70 equalto 1400, so the answer is 14.**

__Example__
Notice how 70 percent of 20 are also 14.

If you need to calculate the percentage of a number, such as
72 or 29, then round up and down to the adjacent multiple (70 and 30
respectively) to get a quick approximation.

**: Everyone knows that the square root of 4 is 2, but what about the square root of 85?**

__Faster Square Roots__**: Find the nearest square. In this case, the square root of 81 is 9. Determine the next adjacent square. In this case, the square root of 100 is 10.The square root of 85 is a value between 9 and 10. Since 85 is closer to 81, the actual value must be 9 point something.**

__Quick calculation approximately by__**: If twice your money sounds too wimpy and you wish to up the bet by tripling your money, then use the number 115 rather than to guess the number of years it will take your money to triple. For example, an investment at a 5% growth rate would take about 23 years to triple.**

__The Rule of 115__**:-**

__Multiplication of 11 with Any Number of 3 Digits__
“Let me explain this rule by taking examples

352*11 = 3--- (3+5) --- (5+2) ---2 = 3872. Means insert the
sum of first and second digits, then sum of second and third digits between the
two terminal digits of the number

213*11 = 2--- (2+1) --- (1+3) ---3 = 2343”

__Here an extra case arises__:

“Consider the following examples for that

329*11 = 3--- (3+2) +1--- (2+9-10) ---9 = 3619, Means, if
sum of two digits of the number is greater than 10, then add 1 to previous
digit and subtract 10 to the associated digit.

758*11 = 7+1--- (7+5-10) +1--- (5+8-10) ---8 = 8338”

__To Calculate Reminder on Dividing The Number By 27 And 37__
Let me explain this rule by taking examples consider number
34568276, we have to calculate the reminder on diving this number by 27 and 37 respectively.

Make triplets as written below starting from unit’s place
34.....568....276

Now sum of all triplets = 34+568+276 = 878

Divide it by 27 we get reminder as 14

Divide it by 37 we get reminder as 27

**:**

__To Calculate Reminder on Dividing the Number by 3__**- First calculate the digit sum, then divide it by 3, the reminder in this case will be the required reminder.**

__Method__**: - 1342568**

__Example__
Let the number is as written above. Its digit sum = 29 = 11
= 2

So reminder will be 2

**:**

__Square Of Numbers Near To 100__
Let me explain this rule by taking examples 96^2 -

First calculate 100-96, it is 4so 96^2 = (96-4) ----4^2 =
9216

Similarly 106^2 -

First calculate 106-100, it is 6, So 106^2 = (106+6) ----6^2
= 11236

**: If the two numbers differ by 6 then their product is the square of their average minus 9. Let me explain this rule by taking examples**

__Multiplication of Two Numbers That Differ By 6__
10*16 = 13^2 - 9 = 160

22*28 = 25^2 - 9 = 616

**: Let me explain this rule by taking examples**

__Multiplication of 99 With Any Number__
1. 46*99 = 46*(100-1) = 46*100-46 = 4600-46 = 4554.

2. 362*99 = 362*(100-1) = 36200-362 = 35838.
