Have you wondered how cool it would be to have the power of speed like that of the super-hero Flash to solving Math problems? All you need is an attentive mind and some easy techniques which can help you calculate faster. Learning techniques on how to do math quickly can help you develop greater confidence in math, improve math skills and excel in advanced courses!

In Math there is only one correct answer but there can be many different techniques to arrive at it. The traditional mathematical techniques in problem-solving can sometimes be time-consuming or complex or simply boring.

One such technique which has been tried and tested for generations is Vedic Math. This technique can be rather helpful for your arithmetical development and can come very handy as one moves up the academic ladder.

Let us now pick up three simple tips and tricks which will help you calculate faster.

Tricks for Addition

Step 1 Add the numbers which are the multiples of 10s

Step 2 Add/Subtract the deficiency of numbers

Example: Finding a sum of 999 and 128.

Step 1: Add 1000 + 130 = 1130

Step 2: Subtract (1+2) i.e., the deficiency from 1130 = 1127

Find the Square Value

Step 1 Choose a base that is closer to the original number

Step2 Find the difference between the number from the base

Step 3 Add the difference with the original number given

Step 4 Multiply the result with the base

Step 5 Add the product of the square (of the difference) with the result of the above step mentioned

For Example: Finding the Square of 98

Step 1: choosing 100 as base

Step 2: 98-100= -2

Step 3: 98+(-2) = 97

Step 4: 100* 97= 9700

Step 5:

9700+ square of (-2) = 9604

Trick for Multiplication of Any 3-digit Numbers

Find answer to 306 x 308

Step 1: Subtract the unit place digit from the actual number given

From 308-8=300

From 306-6=300

Step 2: Select any 1st or 2nd number to add the unit digit of the number 308+6=314

Step 3: Multiply the product you got in the 2nd step with step 1

314×300 = 94200

Step 4: Now add the unit digits of both the number

8×6=48

Step 5: Add 94200 and 48

94200 + 48 = 94248

Final answer 306 x 308 =94248

Before you share these tips with your friends, remember calculating faster is of no use if we fail to understand the rationale behind the problem-solving. These tricks can do wonders only if you put them to regular practice.
