Every test contains at least one question related to this formula

BODMAS stands for

Bracket off division multiplication Addition Subtraction

Example:

Let us see how we will solve this question which contains all mathematical operations:

5+5-5*5/5=5

Always follow these steps ist / then * then + and at-last -.

Well, it's been so long that i have opened the mathematics book, as i was not in touch with that book , a long ago.So in my case, is it necesary to join an acedemy for the screening test, in order to clear my concepts, or books will be enough for the prepration??

Sir fine job being done I think 45 mins suffices the niceties of maths potion n screening.
Have your say, pease.

basic concepts from matriculation book are enough.you must buy GAT book and chek math portion from that.it will help you in screening.

A problem that involves different operations ( parenthesis/bracket, division, exponents etc) the operations must be performed in a particular order. an east way to remember the order of operations is to memorize the following sentence.
Please Excuse My Dear Aunt Selena
this stands for Parenthesis/brackets, Exponents, Multiplication, Division, Addition and Subtraction. i-e first of all solve the operations enclosed in the parenthesis. then exponents, then multiplication, then division. then addition and in the end subtraction.

Another concept is of MEDIAN.
MEDIAN :
If a group of numbers is arranged in order, the middle number is called the median. but if there is no single middle number ( in case of even number of times) then median can be found out by taking the arithmetic mean of the two middle numbers.
Example : the median of 6,8,10,12 and 14 is 10. Because there are total 5 numbers and 10 is the third number i-e in middle, so it is median.

Example : the median of 6,8,10,12,14,and 16 is ;
10 + 12 / 2 = 22/2 = 11
So 11 is the median.

1. Odd Integers : Any number that cannot be divided by 2 is called an odd integer. For example : -3, -1, 1, 3, 5, 7, 9,11 and so on.
Properties of odd integers :
i. The difference between two consecutive odd integers is 2.
ii. If a is an odd integer, then the next consecutive odd integer will be a + 2.
iii. The sum of two odd integer is an even number.
iv. Product of two odd integers is an odd integer.
v. Division of an odd integer by another odd integer may not be an integer.

2. Even Integers : Any number that can be divided by 2 OR those integers that are multiple of 2 are even integers. For example. -4,-2, 0, 2, 4, 6 and so on.
Properties :
i. Difference between two even numbers is 2.
ii. If x is an even integer, then the next consecutive even integer will be x + 2.
iii. the sum of two even integers is an even integer.
iv. Product of two even integers is also an even integer.
v. Division of an even integer by another even integer may not be an integer.

Next topic will be Prime Numbers.

i dont get the 5th point...

15/3 = 5 Odd Integer

But 13/3 = 4.33 Not integer

v. Division of an even integer by another even integer may not be an integer.

44/2 = 22 even Integer

but
34/4 = 8.5 not integer

In maths section these topics are important,quantitative comparison,average,percentage(very important),ratio n proportion(very important and somewhat tricky )probability(difficult and tricky),algebra(easy).only these 6 chapters cover whole maths part)Best book for maths part is smart brain NTS GAT book by
Muhammad Idrees,use another book like Barrons GRE book(old edition,maths section only)as a refrence only,maths part is not so much difficult,it requires practice and practice,if anyone is very weak in maths,he should use all resources along with book like hiring a teacher,or through skype or youtube maths lectures

All rounder · #39 Friday, July 12, 2013

Maths part is not difficult at all,only requires a little practice daily,30 to 45 min practice is sufficient.Maths questions should be solved through formulas(5 to 10 important formulas are sufficient)or solve through common sense.For screening test give proper time to all subjects

Which are the best notes out of the three ; Ilmi notes ,Caravan and Dogar Publishers available in the market , as far as the screening test is concerned..
