Most of the participants do a similar mistake of learning
formulas without solving the questions but it only waste of time in remembering
the way of answer a question. We have brought up many Short & Easy Tricks
to make Mathematics Easy in this article. Irregular candidates generally make
mistakes that could simply be remedied by reviewing their answers in particular
ways but it requires special focus of the techniques to answer a question
correctly. On this page ejobhub team is going to declare all the required short
& easy tricks to make mathematics easy to prepare for math’s exam.
Shortcut Tips & Tricks To Prepare For Mathematics Exam
Practice, Practice
& More Practice: Applicants are advised to practice as much as
possible to know the best way to solve the questions.
Learn the Key
Concepts: Before start practice for maths know all the key concepts to
know the reason of the problems come in the maths.
Review Errors:
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.
Join a study group:
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.
Short and Easy tricks to make mathematics easy:
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.
Faster Percentage Calculation: 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.
Example:
20% of 70? 20 times 70 equalto 1400, so the answer is 14.
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.
Faster Square Roots: Everyone knows that the
square root of 4 is 2, but what about the square root of 85?
Quick calculation
approximately by: 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.
The Rule of 115: 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.
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:
Method-
First calculate the digit sum, then divide it by 3, the reminder in this case
will be the required reminder.
Example: -
1342568
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
Multiplication of
Two Numbers That Differ By 6: 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
10*16 = 13^2 - 9 = 160
22*28 = 25^2 - 9 = 616
Multiplication of
99 With Any Number: Let me explain this rule by taking examples
1. 46*99 = 46*(100-1) = 46*100-46 = 4600-46 = 4554.
2. 362*99 = 362*(100-1) = 36200-362 = 35838.
