Tell me, how much time will you take to subtract a number from 100’s multiple such as 1000, 1000, 10000? 1 min or less? Leave that, try to calculate with this new formula and think if it’s easy & reduce your calculation time or not!
For example:
1000 – 573 =? (Subtraction from 1000)
We simply subtract each figure in 573 from 9 and then subtract the last figure from 10.
Step 1. 9 – 5 = 4
Step 2. 9 – 7 = 2
Step 3. 10 – 3 = 7
So, the answer is: (1000 – 573) = 427
Here are some practice sums for you. Try to solve these sums using the mentioned Vedic Math Tricks.
1000 – 857, 10,000 – 1029, 10,000 – 1264, 1000 – 336.
2. Multiplication Of Any 2-digit Numbers (11 - 19)
Till Math is there, you need to do such calculation each & every day, whether you are from CBSE board or ICSE Board. This Vedic Trick is especially for getting the result when you multiply any two-digit number from 11 to 19.
Once you practice this Vedic Trick for a number of times, you might never need a calculator to get the result as you will calculate faster than the machine.
There are 4 steps to get the result:
Step 1. Add the unit digit of the smaller number to the larger number.
Step 2. Next, multiply the result by 10.
Step 3. Now, multiply the unit digits of both the 2-digit numbers.
Step 4. Then add both the numbers.
For example: Let’s take two numbers 13 & 15.
Step 1. 15 + 3 =18.
Step 2. 18*10 = 180.
Step 3. 3*5 = 15
Step 4. Add the two numbers, 180+15 and the answer is 195.
Hope you have understood this Vedic Math Trick. It might seem a bit complex at first, but trust me once you master it, your calculation speed will increase by at least 80%. And, that is something every student needs to score well in Math!
Using this Vedic Trick, solve these sums and share your result: 15*18, 11*13, 19*19
