Numbers for GMAT Quant
Part 2: https://gmatclub.com/forum/a-must-read- ... 70800.html
Part 3: https://gmatclub.com/forum/a-must-read- ... 70926.html
Numbers have always fascinated us. You can love them, you may hate them, but you just cannot take them out of your lives. Numbers are to Math as alphabets are to a language. On standardized tests like the GMAT, the topic of Numbers is given a lot of importance. This is because of a multitude of reasons:
Not only this, a lot of topics like Inequalities, Absolute Values, Statistics, Probability, P&C and Geometry, require you to be very good with your knowledge of Numbers and leverage them in understanding the data provided as well as the implied ideas, in answering the questions.
So, we thought it to be a great idea to post articles about important aspects of some amazing numbers and make it easy for y’all to improve your strike rate in questions from this topic, which constitutes a significant chunk of questions in the GMAT Quant section.
Of course, you can already find a lot of posts made by some great guys here on GMAT Club on this topic, but, hey hang on, go through our posts here and we assure you that you’d not be disappointed.
What are Numbers?
Come to think of it, as kindergarten goers
, we learned numbers by learning how to compare big and small, long and short, thick and thin etc., - an activity that was focused on identifying the commodity that had more quantity. This was our pre-cursor to learning Numbers.
A number is a way of quantifying data i.e., numbers are used to denote quantity and are usually the result of a measurement / act of counting.
Of course, there are people who argue that the creator was a Mathematician, there are people who also like to think that animals can count and stuff like that, but the reality is that humans have contributed their biggest share to the understanding and evolution of Math. And it all probably started with Numbers when we were still hunter gatherers.
Why are we partial towards certain numbers??
As humans, we probably started counting using our fingers (probably why both are called digits
) and it’s no wonder that we still can’t let go of positive integers – this is one trap that many GMAT test takers fall for when solving questions on Numbers. Well, at least in this case, thinking positive isn't always good for our answers 
As we evolved, so did our sense of numbers and therefore the subject of Maths.
The discovery of Zero was of course a watershed moment in the history of Mathematics but, so was the nomenclature of √−1 as an imaginary number.
As a result of all these important events in the history of Math, the classification of the Number system is fairly solidified by now. The world of numbers for a GMAT aspirant comprises only of real numbers, which are then classified into Rational, Irrational, Integers, Fractions, Primes, Co-primes and so on.
However, our objective here in this article will not be discuss all the different types of numbers but to focus on some special numbers that show up very often in GMAT Quant questions. So, what are we waiting for? Let's see what these numbers are.
The Trio that needs (NO) introduction!
Among all of these different numbers, the simple guys get trampled over by some others, are forgotten/ignored/just don’t yield themselves to our calculations, naturally. In this article, we would like to focus on three such numbers who are simpletons and like most simpletons, they pull their weight around and can turn things on their head; in short, you can ignore them at your own peril, especially on the GMAT.
Unlike a lot of us, GMAT does give these numbers the credit they deserve and puts them in a lot of questions – sometimes in very obvious ways, and in some other cases, in very subtle ways to create traps.
These numbers are – lo and behold - Zero, One and Two. So, a lot of you are probably wondering, “Wait, what? These are the special guys?
Improbable, right?” Wrong! 
These are indeed the numbers which get tested very often in questions on Number Theory on the GMAT.
As such, this three-part article will focus on discussing the specialties of these numbers, right from the very obvious to the least conspicuous.
For a start, we will start with ZERO in the second part of this article, tomorrow. After all, in some branches of Math, Zero represents the Origin, so it’s only fair that we start with ZERO.

On standardized tests like the GMAT, the topic of Numbers is given a lot of importance. This is because of a multitude of reasons:
- Numbers form the foundation of all that is there to Math.
Number Theory is also a vast topic and offers a lot of scope in terms of nuances, for the GMAT to test.
Number Theory also forms the basis for the entire section of Arithmetic (fun fact: Arithmos in Greek means the art/craft of dealing with Numbers).
Not only this, a lot of topics like Inequalities, Absolute Values, Statistics, Probability, P&C and Geometry, require you to be very good with your knowledge of Numbers and leverage them in understanding the data provided as well as the implied ideas, in answering the questions.
