## Tricks

The GMAT quantitative tricks are very beneficial for the students. If these math tricks are followed it will land a student answering the question without even solving any use of calculators. Glance through some of the main math tricks that will help you crack the questions easily.

### Do Difficult Calculations using Multiples of 10

Since, multiplying any number to 10 is quite fairly easy, you can use this maths trick for carrying out calculations in the GMAT. For example, you need to add or subtract a number which isn’t a multiple of 10, then the best way to do it is to round off the number by 10 or its multiples and then add or subtract. Let’s take an example:

725+211
=700+211+25 =911+25
=936

Another way to use this amazing maths trick is for multiplying and dividing. Suppose you have to multiply n by 18, start with breaking them down into multiples of 10, use this formula of distributive property:

n*18= (n*10)+(n*8).

Using this math trick, you can add, subtract, multiply and divide in a simpler way!

### Squaring Numbers Between 11 and 19 by using 10

Maths tricks for squaring numbers are quite few but this one is surely easier! In order to square any number x that comes between 11 and 19, you need to first find the nearest multiple the number has from 10 and then calculate how much you need to add or subtract to make it a multiple of 10. Let’s suppose that the number you need to add or subtract is n. Now, you need to do the opposite of n with x, so the nearest multiple of x you get after subtracting n then you need to add it in the formula and vice versa.

Square of x = x (x+n and x-n)

For example, Square of 22= (20*24) + Square of 2
=480+4
=484

### Weigh Options Methodically in Data Sufficiency

Since Data sufficiency amounts for a wider portion in the GMAT, there are many maths tricks that can prove to be extremely helpful. This trick utilises the idea of elimination for cracking data sufficiency questions. For any question, the choices you have been given, you need to go through them in the same order they have been provided. Don’t confuse yourself by checking the option ‘c’ first or any other, but go from ‘a’ to ‘e’ methodically.

### Simplifying the Confusion of Square Roots

When you are provided with a number which is a square, many think that it might be a square root of a positive number. Amongst many useful maths tricks, this one reminds you that a square root can be of a negative or a positive number so it is better not to assume only positive number for it. So, if you are given a square of a, its root might be a positive or a negative number!

### Use Quick Approximation for Problem-solving

Problem-solving is another tricky giant in the GMAT exam which you must gear up for. Out of the many tricks you can use for problem-solving, the significant one is to use estimation and elimination for your answers. Let’s suppose that you need to multiply a number by a complex fraction like 12/45, which will come somewhere at 0.2. Here, you are not really required to find the exact answer by dividing this all the way, so, tick the choice which comes the most closer to 0.2 which will probably get you to the actual answer!
